For binocular head microscope, we also should do some
more adjustments:
(1) Hold the two ends of the head-cover and adjust the
interpupillary distance by pushing or pulling the cover, until
one circle of light can be seen.
(2) After finishing the interpupillary adjustment, look at the
graduation value in the middle of the head-cover. Turn the
two diopter-ring and aim the same graduation value at the
graduation line on the eyetube.
Avoiding decline of the stage, rotate the tension knob in a
clockwise direction to give a suitable force to the stage. If
we need to reduce the tension, rotate the tension knob in an
anti-clockwise direction.
2-5 Adjust diopter of binocular head
If the diopter of the two eyes is not same, binocular head
microscope has compensating function.
Turn the nosepiece to choose the objective 4X, and use the
left eye to observe the left eyepiece. Adjust fine-focusing-
knob and focus correctly. Use right eye to observe the right
eyepiece. Gain the clear image by turning the diopter-ring
up and down.
2-6 Adjust condenser
Turn the condenser-adjustment-knob to make the condenser
move up or down to concentrate light and to get the image
brightness suitable for observation.
2-7 Adjust diaphragm
Adjust the aperture of the iris diaphragm to get the
background brightness suitable.
