4. INSTRUMENT CONFIGURATION AND FUNCTIONS
Stereo Configuration:
4.1 Main body
:
The optical body supplies a 1:6.7 zoom ratio of GM-171 and 1:6 zoom ratio of GM-161, which
provides the microscope with long depth of field and stereoscopic capability. Throughout the
magnification change process, the microscope remains parfocal and parcentered (for specific
alignment and calibration instructions see the Microscope Adjustment and Operation section).
The zoom adjustment knobs (Fig.3) are located on both sides of the optical body, rotate these
knobs to change the magnification strength. For the specific magnification strength, see the values
on the adjustment knob (the current magnification strength is aligned with the 0 on the body).
The optical body is inserted into the microscope carrier and the holding screw located on the left
side of the carrier is used to secure the body to the frame.

4.2 Binocular Observation Tubes: (GM-171B)
Equipped with N-WF10X/F.N.23 eyepieces.
Adjust the two eyepiece tubes to adjust the interpupillary distance (interpupillary adjustment range:
48-75mm).
The diopter adjustment rings on the eyepieces are used to adjust the diopter scale (±5°) of the
eyepieces.
