A. OUTLINE OF PRODUCT 


1, OUTLINE 

(1) Application 

Clinical inspection for diagnosis of disease, cells, blood, etc. 
and general researches. 

(2) Product range 

Replacement product range of BHT and BHTU market. 

2. FEATURES 

(1) The field number 22 (standard field of view) is used to expand the 
observation range 20% compared with the BH2. 

(2) The arm rest (base) is eliminated to allow the operator to directly 
put his hand on the table surface, minimizing the operator's fatigue 
and improving the maneuverability. 

(3) The base-less structure expands the operation space. 

(4) The eye point height is adjustable to meet the operator when combined 
with U-TBI, minimizing the operator's fatigue and improving the 
workability. 

(5) The wide field of view (field number 26.5) is available when 
combined with the superwide field observation tube. 

(6) The new glass material and coating agent used in the UIS optics 
provide an image with sharp contrast. 

(7) The ceramic coated stage is equipped as a standard to 
minimize the friction of the slide glass on the stage surface. 

(The wear resistance is improved to eight times or more than the 
BH2-SVR(L).) 

(8) The stage control knob's rotating force is adjustable by the user 
(40 - 400g in each of the X and Y direction). 

(9) The revolving nosepiece facing the rear side is used to facilitate 
visual inspection and marking of a specimen. Since the intermediate lens 
is not built in the revolving nosepiece, it prevents deterioration of an 
image by the intermediate lens and allows the U-excited observation. 

(10) The light preset switch allows one-touch switching to the desired light 
level. (This is useful for setting the color temperature of photography 
and light intensity adjustment when switching between two objectives.) 

(11) The stage stroke is increased and the interference between the 
specimen holder and the 40x objective is eliminated to enable 
observation of the whole surfaces of two slide glasses. 

(12) The illumination switch, the light intensity control and the coarse 

and fine adjustment knob are located in a concentrated position to allow 
operation by minimum handling. 

(13) The advanced computer simulation based on the finite element method(FEM) 
is employed to improved the rigidity and stability of the micro¬ 
scope frame. 

(14) The 30W halogen bulb is used to increase brightness and to allow 
special observation such as darkfield and phase contrast.

to avoid scratching any parts or touching glass surfaces. 



Fig. 2 




A-2C 





The fork and mirror assembly is for use when a source of electricity to power the built-in illuminator is not available. A strong 
light source ie. sunlight, jeep headlight, bright flash light etc., reflected off the mirror is required to provide proper illumination. 




Fig. 65 



1. Raise the condenser up to its maximum height using condenser knob (T) 
be careful not to run the stage up into the objectives. 

2. Carefully insert the base of the fork and mirror assembly into the light well © 
of the microscope. 

3. Turn assembly © so that the mirror is facing front and adjust the angle 
to 45 degrees.

USING THE CONTROLS 





1. Sliding the light intensity lever a upward increases the voltage, making 
illumination brighter. 

2. The numerals to the right of the LEDs of the voltage indicator ( 2 ) indicate 
the voltage. 



The light preset button (T) makes it possible to set the light intensity to 
a preselected level regardless of the position of the light intensity lever. 

1. Push the light preset button Q to the ON position. 

(The face of the switch lights when the switch is ON.) 

2. Using a small screwdriver, turn the preset adjustment screw to obtain 
the required light intensity. Turning the screw clockwise increases 
intensity. 

3. Switch the light preset button OFF and brightness returns to the level 
set by the light intensity lever. 

★ The light intensity lever does not affect brightness while the 
light preset button is ON. 


— Using the Light Preset Button - 

The light preset button allows you to temporarily adjust brightness to a preset level for applications such as 
photomicrography, making it unnecessary to manually adjust the brightness each time you take a photograph. 

• Before shipment from the factory, the preset level is set to an intensity that is suitable for photomicrography. 

• The light preset button is also useful when using two different objectives alternatingly, allowing you to avoid 
manually adjusting the brightness each time you change magnifications. 



G 

You can place to two 45 mm diameter filters into the filter holder on 
the light exit at the base of the microscope. If you need to use more 
than two filters at once, use a filter cassette. 

★ When using a filter cassette, you can additionally use a single 
filter with a thickness of less than 3 mm over the light exit glass.

1. Turn the condenser height adjustment knob © and raise the condenser 
to its upper limit. (Fig. 34) 

2. Focus on the specimen using the 10X objective. 

★ When using the U-SC swing-out condenser, move the front lens 
into the light path. 

3. Rotate the field iris diaphragm ring © in the direction of the arrow to 
reduce the aperture. 

4. Turn the condenser height adjustment knob © to where the image of 
the iris diaphragm is visible in sharp focus. 

5. Turn the two condenser centering screws © to move the image of the 
field iris diaphragm to the center of the field of view. 

6. Gradually open the field iris diaphragm. The condenser is properly centered 
if the iris image is centered and inscribed in the field of view.. 

7. During actual use. increase the field stop slightly so that its image is 
just outside the field of view. 



Fig. 53 



Field Iris Diaphragm _ (Fig. 53) | 

The field iris diaphragm restricts the diameter of the beam of light 
entering the condenser and thus excludes extraneous light, improving 
image contrast. The diameter of the field iris should be adjusted for 
objective power to the extent that it lies just outside the field of view. 
(See "Compatibility of objectives and condensers" on the next page.) 
When photographing specimens, stop the field stop down to where it 
is somewhat larger than the firm format © to obtaimeven better results. 





A-17 













Aperture Iris Diaphragm _ (Figs. 54, 5 5) 

• The aperture iris diaphragm determines the numerical aperture of the 
illumination system. Matching the numerical aperture of the illumination 
system with that of the objective provides better image resolution and 
contrast, and also increases the depth of focus. 

• Since the contrast of microscopic specimens is ordinarily low, setting 
the condenser aperture iris diaphragm to 70-80% of the N.A. of the 
objective in use is usually recommended. When necessary, adjust this 
ratio by removing the eyepiece and peeking into the eyepiece sleeve 
to see the image shown in Fig. 54. 



Fig. 55 


Using the Numerical Aperture Scale _ | 

Set the condenser numerical aperture to about 80% of the NA value 
(2) indicated on the objective. (Fig. 55) 

Example: With the Plan 40X (NA 0.65), set the scale to 0.65 x 0.8 
= 0.5. 


Compatibility of Objectives and Condensers 



•'When using the U-SC swing-out achromat condenser together with the 2X or 4X 
objective, fully open the condenser aperture and use the field iris diaphragm in the 
base as aperture diaphram. 

* ? Although slightly inadequate NA results in a somewhat darker field of view with a 
100X objective, the combination is usable. 

• To obtain better illumination, use of the U-ULC is recommended in photomicrography 
when using the 2X or 4X objective. 

















BX40 





Ad|ust the coarse adjustment knob tension using the tension adjustment 
ring. 

The coarse adjustment knob tension is preadjusted for easy use. However, 
if desired you can change the tension using the tension adjustment 
ring 0. Turning the ring in the direction of the arrow increases tension, 
and vice versa. 

The tension is too low if the stage drops by itself or focus is quickly 
lost after adjustment with the fine adjustment knob. In this case, turn 
the ring in the direction of the arrow to increase tension. 



Fig. 57 



Ordinarily, the fine adjustment knob is used with the rubber cap attached. 
However, if space between the knob and the stage knobs is insufficient, 
the cap may be removed. The cap makes it easier to turn the fine 
adjustment knob, allowing more accurate focus. 




The coarse adjustment stopper serves to keep the objective from w 
bumping into the specimen and to simplify focusing. After focusing on 
the specimen with the coarse adjustment knob, turn this lever 0 in 
the direction of the arrow to set an upper limit on the coarse adjustment 
movement. After changing specimens, refocussing is easily accomplished 
by turning the coarse adjustment knob to the stopper position, then 
making fine adjustments with the find adjustment knob. 

Stage movement with the fine adjustment knob is not affected by this 
stopper. 


A— 1 Q 












Fig. 59 


Use of.Immersion Objectives (Fie 59) 


1. Focus on the specimen with a low power objective. 

2. Place a drop of immersion oil (provided) onto the specimen at the 
portion to be observed 

3. Turn the revolving nosepiece to move the oil immersion lens into the 
light path, then focus using the fine adjustment knob. 

If the condenser marking shows a numerical aperture (NA) of 1.0 or 
more, the number applies only when oil is present between the slide 
glass and the top element of the condenser. When oil is not present, 
the NA is about 0.9. 

★ Since any bubbles in the oil will impair the image, make sure 
that the oil is free of bubbles. 

a. To check for bubbles, remove the eyepiece and fully open field 
and aperture iris diaphragm, then look at the exit pupil of the objective 
inside the observation tube. (It should appear round and bright.) 

b. To remove bubbles, rock the nosepiece slightly to move the oil 
immersion objective back and forth a few times. 

4. After use, remove oil from the objective front lens by wiping it carefully 
with gauze dampened with a very small quantity of 7 parts ether: 3 
parts alcohol solution, or with Xylol. 

★ Using too much Xylol can dissolve the lens adhesive. 



• Use a trinocular observation tube (U-TR30) for taking photomicrographs. 

Photomicrograph can be performed using either the PM-10, the PM-20, or the PM-30 photomicrographic system. Procedures 
for using the photomicrographic unit are described in respective instruction manual. Procedures specific to this microscope 
are given below. 




1. Using the Allen wrench, loosen the clamping screw © on the trinocular 
lens photo tube. 

2. Align the vertical index line © with the index dot © on the single port 
tube, then insert the single port tube into the photo tube. 

3. Securely tighten the clamping screw ©. 


Fig. 60 













Photo.-Eyo piece 



Use the PE photo eyepiece for photomicrography. Insert photo eyepiece 
© into the dinhlr port tube on the trinocular observation tube. 



Fig. 62 



Place the photographic unit directly over the circular dovetail of the 
trinocular observation tube. Make sure that the index dots © on the 
observation tube and the unit are aligned, then clamp the unit. 



See page 15 of the "Observation Tube" section. 




1. Focusing is done using the binocular eyepiece part of the trinocular 
observation tube. 

★ Whenever you remove the viewer from the photographic unit, 
be sure to install the cap. 

2. Insert a finder eyepiece into the right eyepiece sleeve. 

3. The finder eyepiece has a built-in focusing lens with four masks, and 
the focus is practically the same for the focusing lens and the camera 
film plane. The masks indicate the areas covered, and the numerals 
next to the masks correspond to the magnification of the photo eyepiece. 
Different finder eyepieces are available for different cameras. Select 
the type that is appropriate for the camera being used. 

4. Because of the great depth of focus of 1X to 4X objectives, use of the 
illuminated focusing telescope (U-FT) is recommended for accurate 
focusing. 

• Focusing is easier using the focusing telescope of the camera unit 
than using the finder eyepiece. 








The fork and mirror assembly is for use when a source of electricity to power the built-in illuminator is not available. A strong 
light source ie. sunlight, jeep headlight, bright flash light etc., reflected off the mirror is required to provide proper illumination. 


1. Raise the condenser up to its maximum height using condenser knob (7) 
be careful not to run the stage up into the objectives. 


2. Carefully insert the base of the fork and mirror assembly into the light well © 
of the microscope. 


3. Turn assembly © so that the mirror is facing front and adjust the angle 
to 45 degrees. 


4. Shine light source onto mirror while looking through the eyepieces. The 
angle of the mirror may need to be adjusted to get maximum light intensity.

AND PHOTOMICROGRAPHY 


Microscope components get dirty with time. Dirt and dust particles on the optical components are especially 
damaging to image quality. When photographing important specimens which cannot be rephotographed, visible 
dust particles on the picture can be most frustrating. Therefore, we suggest the following critical microscope 
components be kept clean and dust-free. 


Photoeyepiece 
Remove and clean, since dust particles 
will be focused on the film plane. 


Video Camera 

Wipe dust particles appearing on the 
monitor screen. If the particles move 
only when the specimen or condenser 
is moved, clean the specimen and/or 
condenser. If the particle does not 
move when the CCTV camera is 
rotated, clean the camera chip. 


Eyepieces 
Eyepieces get dirty frequently. Wipe 
carefully and gently so as not to damage 
the lens coating. 


Objectives 
Dirt and dust particles directly affect 
the microscope image. Wipe thoroughly 
and carefully with a cotton swab. 


Condenser 

Dirt and dust particles are easily seen. 
Always dust and wipe clean. 




Filter and light Exit Window 
Dust and dirt particles here have minimal 
effect on the image. However, the overall 
appearance requires frequent cleaning. Wipe 
evenly since this is a wide surface area. 


Built-in Filters 
Difficult to clean. Please consult your 
Authorized Olympus Microscope Dealer. 



Mirror for Large Format Attachment 
Dust and dirt particles here affect pictures. Difficult 
to clean without damaging the mirror surface, we 
advise you to contact your Authorized Olympus 
Microscope Dealer.

CLEANING THE OPTICAL SYSTEM 


Although cleaning the objectives and eyepieces is relatively easy, here are some procedures and simple 
techniques to protect the lens coating and assure optimal performance. 


Required tools: 

• Lens Tissue • Cotton swabs (Q-tips) • Blower • Magnifier • Cleaning Solution: 7 parts of ether and 
3 parts of ethyl alcohol. The mixture ratio depends on room temperature and humidity. When the humidity 
is high, the ratio can be changed to 8 parts of ether and 2 parts of ethyl alcohol. 


Caution: 


Lightly brush the lens surfaces or blow with the blower before wiping with tissue. This removes particles that 
may scratch the lens surface. 


HOW TO CLEAN OBJECTIVE LENSES 



Wet the tip of a cotton swab 
with a generous amount of lens 
cleaning solution. 


With a circular motion, wipe the 
front lens surface with the cot¬ 
ton swab, to thoroughly remove 
any oil or dirt from the lens. 


Dip a new cotton swab in the 
cleaning solution and shake 
vigorously to remove any excess 
solution. 


Wipe the objective front lens 
from the center towards the 
periphery, while rotating the 
lens. 


HOW TO CLEAN THE EYEPIECES 





Wrap a sheet of lens tissue around 
a cotton swab as illustrated. If the 
area to be cleaned is large, wrap the 
lens tissue looser and thicker. Other¬ 
wise, make a thin, tight wrap. 



© 

A 


© 


Dip the wrapped lens tissue in the cleaning 
solution, and wipe the eyepieces from the center 
towards the periphery in a circular motion. 














IMPORTANT NOTES: 

• Do not use the same lens tissue to clean more than one lens. 

• Do not put an excessive amount of cleaning solution on the lens tissue. 

• Blow on the surface of objects to be cleaned before wiping them.

E. REPAIR PROCEDURE 


1. OPTICS CLEANING 

1-1 Precautions 

Dust is not seen through the eyepiece at observation, because it is 
not focused. But, if the dust is stacked, it will affect the observa¬ 
tion brightness and the color temperature in photomicrography. So, 
take precautions to keep your finger away from the optical parts and to 
prevent exudation of grease. Illuminate with the maximum lamp 
voltage to facilitate checking a finger-print and exudation of grease.

A. OUTLINE OF PRODUCT 


1. OUTLINE 

The product is a stage with vertical low drive control to be attached 
to a series of system microscopes. 

The product has two types according to the position of its X/Y knob. 

One is U-SVL (left-hand control) and the other is U-SVR (right-hand 
control). Both U-SVLD(B) and U-SVRD(B) have a specimen holder for two 
specimens. On the other hand, both U-SVLS(B) and U-SVRS(B) have a 
specimen holder for one specimen. 

The (B) added at the end of the model, like U-SVLD(B), indicates the X/Y- 
knob for the long length type (25mm longer than the ordinary X/Y-knob). 

2. FEATURES 

(1) The surface of the stage is excellent in resistance to wear and 
takes no scratch because it is coated with melted ceramic. 

(2) The X/Y-KNOB torque can be adjusted by the user. 

(3) Since the X-guide unit is installed in the lower side of the 
stage, pieces of broken glass or dust are hard to enter into the 
guide unit. 

(4) The working ranges of the X and Y-guides are 76mm and 52mm 
respectively. They are wider than those of conventional type. 

(5) The stage can be rotated by slightly unfastening fixed screws. 

(6) The shape of the specimen holder is designed not to interfere 
with objectives up to 40x magnification (except Plan Apo) in the 
height and directions. The whole surface of a specimen can be 
observed. 

(7) Because the stage covers a wide area, large specimens can be 
placed on it. 

3. USING CONDITIONS 

(1) The stages cannot be installed in frames other than BX frames 
(BX40, BX50, BX60, BX60M), and AX frames. 

(2) Operating temperature range 0 - 40°C

3. JENTSH AND SIEDENTOPF 


Binocular tube has the mechanism to adjust the distance between left 
and right optical axes to meet the observer's eyes. This mechanism is 
available in two typical types: Jentsh which changes the distance in 
a straight line and Siedentopf which change the distance in an arc. 
Each type has merits and demerits. The features of each type are as 
shown below. 


JENTSH 


SIEDENTOPF 



• The center prism is fixed. 

The interpupillary distance 
is adjusted by moving the 
left and right prisms in 
parallel to each other. 

• Less possibility of optical 
axis displacement caused by 
changing the interpupillary 

£ distance. 

g • The reticle glass in the 
jjj eyepiece does not incline 
£ even if the interpupillary 
distance is adjusted. 

• The optical tube length changes 
as a result of the change in 
the light path length when the 
interpupillary distance is 
adjusted. 

• Compact design. 


The left and right prisms have 
the function of a center prism. 

The interpupillary distance is 
adjusted by moving these prisms 
in an arc centering the optical 
axis going up from the objective. 
The optical tube length is not 
changed even if the interpupillary 
distance is adjusted. 

The interpupillary distance 
does not change even if the 
eyepiece is pushed during obser¬ 
vation. 

The reticle glass in the eye¬ 
piece inclines when the inter¬ 
pupillary distance is adjusted.

5, OPTICS ADJUSTMENT MECHANISM 


5-1 Optical axis 



Adjust the optical axis at the above two points. The internal prism 
position is adjustment-free in principle. 

Adjustment (T) 

Adjust the revolving axis in the right sleeve. ("Revolving axis" 
means the mechanical rotation center upon interpupillary distance 
adjustment and the phenomenon which occurs when the optical axis is 
displaced. The optical axis mentioned here is the center of the 
sleeve. Align the optical axis with the mechanical rotation center 
by changing the sleeve position so that the image in the field of 
view does not move upon observation.) 

The left sleeve is used to adjust only the left/right optical axis. 
(Align the right sleeve center with a point of a specimen beforehand, 
then match the left sleeve center with the point of a specimen.) 

Adjustment (2) 

Almost the same as the adjustment method performed for installation 
of the BI unit of the conventional BH2-BI. Mount the standard 
objective on the adjusted frame. Mount the BI unit with the standard 
eyepiece attached to the right sleeve on the frame. Change the BI 
unit mounting position so that the cross center of a specimen co¬ 
incides with the cross hairs center of the standard eyepiece.)

Set the observation state, use the 
standard eyepiece KN0048 + KC2049 and 
observe a specimen whose center can 
be identified (e.x., an concentric 
circle). Align the centers of the 
specimen and the visual field taking 
the right side sleeve as a standard, 
then check the centers displacement 
in the left sleeve by reading the 
reticle scale (1 graduation = 0.1mm) 
of KN0048.

Set the interpupillary distance to 
about 62mm, combine the standard 
eyepiece (KN0048 + KC2049), the 
microscope frame (product) and the 
standard objective (KN0041), then 
check the displacement in the 
centers of the specimen and the 
visual field in the right sleeve by 
reading the reticle scale (1 gradua¬ 
tion = 0.1mm) of KN0048.

Set the interpupillary distance to 
about 62mm (refer to "Interpupillary 
distance adjustment" above), combine 
the standard eyepiece (KN0048 + KC2049 
+ FT-36), the microscope frame(product) 
and the standard objective (KN0041), 
then check the displacement in the 
intermediate image between the right 
and left sleeves by reading the 
helicoid scale of the KN0048. 

Difference 
between left 
and right 
tube length 

less than 1mm 

Set the diopter at "0”. Put a rigid 

flat plate across the left and right 

tube surface, insert a 1mm thickness 

gauge between the flat plate and the 

tube surface. If the clearance is greater 

than 1mm, the unit is out of specifications.
