OPERATION

The stage plates fit into the circular opening in the base. The clear plate can be used for

both reflected and transmitted illumination.

Colored background can be achieved

placing suitable material beneath the plate, for contrast, etc. The frosted plate is used

with reflected illumination. The plate is frosted white on one side, and black on the

other.

If the specimen is white or brightly colored, use the black side of the plate to

increase image contrast

darkening the background. For dark or black specimens, reverse

the plate with the white frosted side facing the objective.

1. Tension Adjustment of Focusing Knobs

This focusing mechanism makes its motion freely

adjustable

for

either

heavy or light movement

depending on the observer's preference. To adjust

the tension hold the two focusing knobs with both

hands and slightly rotate them in the opposite

directions, at the same time.

clamp it with the stage clips, if necessary. (Fig. 2)

3. Interpupillary Distance Adjustment

hands and push or pull the tubes in the arrow

a) Looking through the right eyepiece with your right eye, focus on the specimen with

the focusing knobs.

NOTE: In case of the Model VMT or Model VMZ. ascertain that the high magnification

objectives are used for this adjustment.

b) Look at the image through the left eyepiece with your left eye, and rotate the diopter

adjustment ring

to focus on the specimen, without using the focusing knobs. (Fig. 4)

NOTE:

If accurate interpupillary distance and diopter adjustments are not accom-

plished, prolonged observation would put considerable strain on the observer's

eyes.
