Adjusting the Interpupillar Distance

While looking through the eyepieces, adjust for binocular vision until the

left and right fields of view coincide completely. The index dot · indicates

the interpupillary distance.

}Note your interpupillary distance so that it can be quickly duplicated.

Adjusting the Diopter

1. Looking through the eyepiece without the diopter adjustment ring, rotate

the coarse and fine adjustment knobs to bring the specimen into focus.

2. Looking through the eyepiece with the diopter adjustment ring, turn only

the diopter adjustment ring @ to focus on the specimen. (Fig. 22)

Using a Finder Eyepiece

1. Looking through the right eyepiece with your right eye, turn the top of the

eyepiece ² until a clearly defined double crossline can be seen in the

field of view. (Fig. 22 & 23)

2. Looking through the right eyepiece, rotate the coarse and fine adjust-

ment knobs to bring the specimen and double crossline into simulta-

neous focus.

3. Looking through the left eyepiece with your left eye, turn the diopter ad-

justment ring @ to focus on the specimen.

Using a Super Widefield Observation Tube

Adjust the diopter as instructed above.

However, since no diopter adjustment ring is provided, turn the top of

the eyepiece instead.

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.
