Olympus CH30 - Observation Tube Adjustments; Interpupillary and Diopter Adjustment

CH30/CH40
Placing the Specimen Slide with One Hand
Place the specimen slide at the front of the stage, then slide the specimen slide on the stage surface to slowly and
gradually open the curved finger in the direction of the arrow. Insert the specimen slide into the specimen holder
Until itis fully and properly seated in the specimen holder.
Use cover glasses of 0.17 mm thickness in combination with objectives marked with the “160/0.17" engraving for
optimum performance of these objectives.
‘Specimen slides with a thickness between 0.9 mm and 1.2 mm are recommended for CH30/CH40 microscopes
Using thicker specimen sides may prevent correct formation of the field iris diaphragm image on the specimen surface
and illumination will not be correct in case of darkfield observation

Moving the Specimen (Fig. 18)
Turning the Y-axis knob @ moves the specimen in the Y-axis direc-
tion. Turing the X-axis knob @ moves the specimen in the X-axis
direction.
* Never move the specimen by holding the specimen holder or
‘stage directly as this will damage the knob rotation mechanism.
k When further movement of the stage or specimen holder is
prevented by the provided limiting mechanism, the tension of
the Y-axis and X-axis knob rotation will increaso. At this point,
iting mechanism.
© Adiusting the interpupitiary Distance (Fig. 19)
While looking through the eyepieces, adjust for binocular vision until
the left and right fields of view coincide completely.
Adjust so that the two index dots + are horizontal.
‘© Placing the interpupilary distance indexes so that they are parallel
with the horizontal lines faciitates the adjustment
Also keep the dots parallel with the horizontal lines in case of
interpupilary distances other than 60, 60, 70, and 76.
© Nate your interpupilary distance so that it can be quickly duplicated
Diopter Adjustment (Fig. 20)
1. Looking through the right eyepiece with your right eye, rotate the
coarse and fine adjustment knobs to bring the specimen into focus.
2. Looking through the left eyepiece with your left eye, turn the diopter
adjustment ring © to focus the specimen.
