IMPORTANT

1. A microscope is a precision instrument. Handle it with care and avoid subjecting it to sudden or severe impact.

2. The BX53/BX51/BX41 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.

4. When disposing of the microscope, check the regulations and rules of your local government and be sure to observe them.

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.

Fig. 1

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 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.

CAUTION

BX53/51/41-P

Insert the 10X or 20X objective into the primary hole (position where black

rubber plugs are inserted into the centering holes on the nosepiece).

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.

3Mounting the Objectives (Fig. 4)

When Using Intermediate Attachment for conoscopic and orthoscopic

observation (U-CPA)

Always make sure to mount this unit in such a manner, that it is

parallel to the arm.

Intermediate Attachment for orthoscopic observation (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 @.
