IMPORTANT
This unit employs a UIS (universal infinity system) optical design, and should be used only with UIS
eyepieces, objectives, condensers, etc. Less than optimum performance may result if inappropriate
accessories are used.
1. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.
2. The BX51/52 series microscope can be used with up to two additional intermediate attachments (e.g., U-DO3 dual-
viewing attachment, U-CA or U-ECA magnification changer, etc.). When using an additional intermediate attachment,
please make sure with your Olympus representative or the latest brochure.
3. Do not use the microscope where it is subjected to direct sunlight, high temperature and humidity, dust or vibrations.
Install it on stable, level bench. For operation environment conditions, see SPECIFICATIONS on page 28.
If the microscope is used in a manner not specified by this manual, the safety of the user may be imperiled. In addition, the
equipment may also be damaged. Always use the equipment as outlined in this instruction manual.

2-2 Detailed Assembly Procedure
1Attaching the Stage (U-SRP) (Fig. 1)
1. Turn the coarse adjustment knob @ to lower the substage assembly ² to
its lower limit.
2. Loosen the centering knobs ³.
3. Position the stage with the vernier scale | in front, and carefully lower the
stage onto the round dovetail on the stage bracket ² with the positioning
pin on the stage aligned with the groove on the front of the stage bracket,
then loosely tighten the centering knobs.
Mounting Stage Clips and Mechanical Stage (U-FMP) (Fig. 2)
· Insert the stage clips securely into any two holes ƒ on the stage top
surface.
· Mount the mechanical stage so that the positioning pins on the under-
side fit into the positioning holes … on the stage top surface. Using the
Allen screwdriver provided with the BX51/52 microscope frame, tighten
the clamping screw.

1. Turn the coarse adjustment knob @ to raise the stage to its upper limit.
2. Turn the condenser height adjustment knob ² to lower the condenser
holder to its lower limit.
3. Loosen the condenser clamping screw ³.
4. Position the condenser with the scale markings in front, insert it into the
substage fork as far as it will go.
Align the positioning pin at the back of the condenser with the groove in
the substage fork. Swing the top lens out of the way before inserting the
condenser.
5. Tighten the condenser clamping screw, then raise the condenser to its
upper limit.

#Insert the 10X or 20X objective into the primary hole (position where
black rubber plugs are inserted into the centering holes on the nose-
piece).
Mount the other objectives in such a manner, that the magnification in-
creases from low to high power in a clock-wise direction from the primary
hole.
4Mounting the Revolving Nosepiece (U-P4RE) (Fig. 5)
1. Turn the coarse adjustment knob to lower the stage all the way.
2. Using the Allen screwdriver, loosen the nosepiece clamping screw @ on
the microscope frame.
3. Carefully slide the nosepiece along the dovetail to its limit, in the direction
of the arrow.
4. Clamp the nosepiece by tightening the nosepiece clamping screw.

When Using Polarizing Intermediate Attachment (U-CPA)
#Always make sure to mount this unit in such a manner, that it is
parallel to the arm.
Intermediate Attachment for AN360P (U-OPA)
#The position of this intermediate tube can be adjusted later. At this
point, place the tube so the nameplate is toward the rear.
1. Using the Allen screwdriver, loosen the observation tube clamping screw
@ on the microscope frame.
2. Insert the circular dovetail mount at the bottom of the intermediate
attachments into the opening on the microscope frame and clamp
by tightening the clamping screw @.

1. Using the Allen screwdriver, fully loosen the observation tube clamping
screw @ on the intermediate attachment.
2. Insert the circular dovetail mount at the bottom of the observation tube
into the opening on the intermediate attachment, placing the observation
tube to point the binocular eyepieces towards the front. Fasten the
observation tube by tightening the clamping screw.
7Mounting the Eyepieces
Insert the eyepiece with cross lines into the right hand eyepiece sleeve.
Make sure the eyepiece is inserted so that the positioning pin on the
eyepiece is inserted into the groove at the lower end of the sleeve.
1. Loosen the revolving nosepiece clamping knob @ and remove the
dummy slider.
2. Insert the test plate adapter ² and securely tighten the clamping knob
@.
