This model is furnished with an adjustment for the incidental (top) light. To adjust, move light
directional lever up or down to position the beam of light providing optimum illumination to specimen.
6. INTERPUPILLARY ADJUSTMENT
This permits each user to adjust spacing between eyepieces in order to accommodate distance
between their eyes. While looking through the microscope eyepieces with both eyes, grasp eyepiece
tube housings with both hands and rotate them on their axis, moving eyepieces apart or together until
a full field of view is observed and images blend into one. Interpupillary distance is now corrected for
your own inter-ocular distance and does not require further adjustment later unless another user
changes this adjustment.
7. FOCUSING
A. Rotate zoom control turret to the lowest magnification by aligning the number “1” on magnification
number ring to the white index dot on zoom control turret. Lower magnifications have larger fields
of view, making it easier to position and locate area to be viewed.
B. Place a flat object or specimen slide (cover glass up), on center of stage plate.
C. Turn focusing knobs until object being viewed is in focus.
D. Both eyepieces have knurled diopter adjustment rings. Rotate both left and right diopters in a
clockwise direction to the lowest position.
E. Rotate zoom control turret to the highest magnification by aligning the number “4” on
magnification number ring to the white index dot on zoom control turret.
F. While looking through right eyepiece with one eye, rotate focusing control knob until specimen
comes into sharp focus through right eyepiece.
G. Rotate zoom control turret to the lowest magnification.
H. Adjust the right diopter until the image is sharp. Do not change the focusing knob position.
I.
Without changing the position of the focusing knob, adjust the left eyepiece diopter until you
obtain a sharp image in left eyepiece. the image should now be sharp throughout the zoom power
range.
8. For optimum sharpness of image in the entire field of view, it is important to position your eyes at the
correct point above the eyepieces. Looking through both eyepieces, slowly move your eyes towards
eyepieces to a level where clarity of the entire field of view is achieved. After a brief period of viewing,
you will easily find the best point for your vision.
