Adjusting the Diopter

When diopter adjustment rings are provided on both the left and right, it

is possible to adjust the optimum vision for both the left and right eyes as

described below. The diopter adjustment rings may be provided either on

the eyepieces or the observation tube, and there is no problem even when

the rings are not provided on both of them.

The diopter adjustment ensures parfocality from low to high magnifications

and makes it possible to avoid defocusing even when the objective is

switched.

1. Set the diopter adjustment rings on both sides to scale "0".

2. Engage a high-power objective (40X or so) in the light path, look into

the right eyepiece with your right eye, and rotate the coarse and fine

adjustment knobs to bring the specimen into focus.

} Do not use an oil-immersion objective.

3. Engage a low-power objective (10X or so) in the light path, rotate the right

diopter adjustment ring @ to bring the specimen into focus. Do not touch

the coarse and fine adjustment knobs during the focusing.

4. Looking into the left eyepiece with your left eye, rotate the left diopter

adjustment ring 2 to bring the specimen in focus.

} The above procedure adjusts the diopter with reference to the right eye,

but it is also possible to adjust with reference to the left eye. In this case,

read the above procedure by inverting "right" and "left."

} If an eyepiece equipped with a diopter adjustment ring is inserted into

the side equipped with another diopter adjustment ring of the observation

tube, perform the above procedure without moving the diopter adjustment

ring of the observation tube from the "0" position.

Using the Eye Shades

When Wearing Eyeglasses

Use with the eye shades in the normal, folded-down position. This will

prevent the eyeglasses from being scratched.

When Not Wearing Eyeglasses

Extend the folded eye shades in the direction of the arrow to prevent

extraneous light from entering between the eyepieces and eyes.
