BXFM FOCUSING UNIT This instruction manual is for the Olympus Focusing Unit model BXFM and associated modules. To ensure safety, optimum performance and familiarize yourself fully with the use of the assembled microscope, we recommend that you study this manual thoroughly before operating the unit. Re- tain this instruction manual in an easily accessible place near the work desk for future reference.
BXFM CONTENTS Correct assembly and adjustments are critical for the microscope to exhibit its full performance. If you are going to assemble the microscope yourself, please read chapter 10, “ASSEMBLY” (pages 24 to 27) carefully. IMPORTANT — Be sure to read this section for safe use of the equipment. — SYSTEM DIAGRAM NOMENCLATURE REFLECTED LIGHT BRIGHTFIELD OBSERVATION PROCEDURE...

BXFM 4-2 Focusing Unit Adjusting the Coarse Adjustment Knob Tension (Fig. 6) ² }The rotation tension of the coarse adjustment knob should be adjusted 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 @.
4-3 Observation Tube Adjusting the Interpupillar Distance (Fig. 8) While looking through the eyepieces, adjust for binocular vision until the left and right fields of view coincide completely. The index dot · indicates the interpupillary distance. }Note your interpupillary distance so that it can be quickly duplicated. Fig.
BXFM Using Eyepiece Micrometer Disks (Fig. 12) Eyepiece micrometer disks can be inserted into WHN10X-H (or WHN10X) eyepieces. However, if the eyepiece does not have the helicoid adjustment facility and your eyesight is poor, you may have difficulties in focusing on the ²...
4-4 Reflected Light Illuminator (U-KMAS) Using the Filters (Fig. 15) }Engage the optimum filter sliders for the purpose of observation in the two filter insertion slots @. Be sure to insert them in the direction shown in Fig. 15. The first click position is the idle position and the second click engages the filter in the light path.
BXFM OBSERVATION METHODS (Using U-KMAS) }For the observation methods of the BX-URA2 and BX-RLA2 reflected light illuminators, refer to their instruction manuals. 5-1 Reflected Light Brightfield Observation See “REFLECTED LIGHT BRIGHTFIELD OBSERVATION PROCEDURE” on page 7. 5-2 Reflected Light Nomarski DIC (Differential Interference Contrast) Observation # The performance of polarizer may deteriorate when it has been exposed to light for a long period (about continu- ous 2000 hours).
Page 18
Setting the DIC Slider (Fig. 18) ² 1. Loosen the mounting knob @ on the front of the DIC revolving nosepiece, insert the DIC slider ² so that the surface with indication faces up, and clamp by tightening the mounting knob. 2.
BXFM U-DICRH 1. Adjust the background contrast by turning the prism movement knob | on the DIC slider as described below. (Fig. 18) 2. When the prism movement knob on the U-DICRH DIC slider is turned, the interference color in the background varies from -100 to 100 nm. Set the retardation which can provide best contrast.
Under certain conditions, performance of the unit may be adversely affected by factors other than defects. If problems occur, please review the following list and take remedial action as needed. If you cannot solve the problem after checking the entire list, please contact your local Olympus representative for assistance. Problem...
