Page 7: Assembling Steps
A15.0908 Series 2-2 Assembling Steps 2-2-1 Assemble and Replace the Halogen Bulb ◎For Transmitted Illumination When assembling the halogen bulb for transmitted illumination, hold the bulb① with clean glove or tissue and insert the pins② into the receptacles③. Make sure the bulb is vertical (See Fig. 1). ◎For Reflected Illumination (1) Loosen the lock screw①... - Page 8 A15.0908 Series (2) Push the light source group base ② into the reflected illuminator light source base③ thoroughly, then lock the lock screw①. 2-2-3 Assemble the Condenser (With Polarizer Group) ◎For Transmitted Illumination (1) Rotate the coarse focusing knob① to raise stage to the highest.
- Page 9 A15.0908 Series 2-2-6 Assemble the Epi-Illuminator (1) Loosen the lock screw① of the Epi-Illuminator fully. (See Fig. 9) (2) From a little right position, insert the coattail interface on the bottom of Epi-Illuminator into the hole on the stand with a little left inclined, and then screw down the lock screw.

A15.0908 Series 3-2 Adjust Focusing (1) Put the slice on the stage, hold it with the stage clip. Shift the 5X objective into the light path. (2) Loosen the coarse adjusting limit knob①, observe the right eyepiece with the right eye. Rotate the coarse focusing knob②... -
Page 13: Adjust The Interpupillary Distance
A15.0908 Series 3-5 Adjust the Interpupillary Distance When using two eyes to observe, hold the bases of the prism and rotate them around the axis to adjust the interpupillary distance, until there is only one field of view when binocular observation (See Fig. 19). Interpupillary distance adjustable range: 52~75mm. -
Page 14: Center The Condenser
A15.0908 Series (3) Rotating the stage, turn the black dot to “b”, and adjust the objective in order to move the dot to the midpoint of ab, which is the center “c’. (4) Move the slice to turn the dot from center “c” to point “a”. -
Page 15: Adjust The Field Diaphragm
A15.0908 Series 3-9 Adjust the Field Diaphragm By limiting the diameter of light entering the condenser, the field diaphragm can prevent other light and strengthen the image contrast. When the image is just on the edge of the field of view, the objective can perform best and obtain the clearest image. -
Page 16: Adjust The Analyzer
A15.0908 Series ◎For Reflected Illumination The changing direction of the aperture diaphragm is as same as the field diaphragm, adjust its size by the aperture diaphragm turntable ① . Adjust the two aperture diaphragm centering screws②, to move the image of aperture diaphragm to the center of the aperture (See Fig. -
Page 17: Check H-V Location
A15.0908 Series 3-13 Check H-V Location The system will be in H-V location when both the analyzer and polarizer are adjusted to “0”. In addition, it could be checked under the method as following: no specimen on the stage, take off the eyepiece and the objective, move the Bertrand lens out of the light path, adjust the analyzer to “0”, and rotate the polarizer ajustment ring, observe the brightness changing of... -
