Incidental illumination can be used with either frosted glass plate or black/white plastic stage plate.
Transmitted and incidental illumination combined can provide extra illumination for certain objects where
additional top illumination will enhance the object being viewed.
NOTE: THE TRANSMITTED LIGHT POSITION REQUIRES USE OF BLUE FILTER AND FROSTED
GLASS STAGE PLATE.
2. 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.
3. FOCUSING
A. Turn objective turret so that the lowest magnification number is positioned facing the front of the
microscope. Make certain you turn turret until you hear a “click” which indicates the objective turret is
properly indexed in position. 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 slip up), on center of stage plate.
C. Turn focusing knobs until object being viewed is in focus.
D. Adjust diopter for difference in eyesight. Look into right eyepiece with right eye. Turn focusing knobs
until sharp image is obtained in right side of microscope. Look into left eyepiece with left eye. Adjust
sharpness of image by turning knurled diopter adjustment located on left eyepiece tube.
You have now adjusted the microscope to accommodate any difference between the vision in your left
and right eyes. It should not be necessary for you to make this adjustment again as you change
magnification setting of microscope or objects being viewed.
E. Rotate objective turret so that highest number on turret is positioned facing the front of microscope. Be
sure turret “clicks” into proper index position.
This microscope has been parfocalled, which allows changes from one magnification to another while
requiring no or only slight adjustment of the focusing knobs.
