Adjusting the Diopter

}When using the U-CTBI observation tube, align the white dot " · " on the

diopter adjustment scale on the right eyepiece with the index line before

proceeding to the following adjustment.

1. While looking through the right eyepiece with your right eye, turn the

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

2. While looking through the left eyepiece with your left eye, turn only the

diopter adjustment ring ² to focus on the specimen. (Fig. 13)

Tip

If you switch the objectives frequently

}If you switch the high- and low-power objectives frequently during obser-

vation, a focus error may be produced after switching unless the diopter

is adjusted strictly.

To adjust the diopter precisely, it is required to provide the right eyepiece

with helicoids.

1. Engage the high-power objective in the light path, look through the right

eyepiece and focus on the specimen.

2. Engage the low-power objective in the right path and turn only the helicoids

of the right eyepiece to focus on the specimen.

}The precision can be improved by repeating steps 1 and 2 several times.

3. Look through the left eyepiece and turn only the diopter adjustment ring

to focus on the specimen.

Using a Finder Eyepiece (35WHN10X/PWH10X)

}Insert the finder eyepiece into the right eyepiece sleeve of the U-TR30-2

trinocular tube.

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

top ring until clearly defined double crosslines can be seen in the field of

view. (Fig. 14)

2. Looking through the right eyepiece, turn the coarse and fine adjustment

knobs to bring the specimen and double crosslines into simultaneous

focus.

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

justment ring to focus on the specimen.

Using the Eye Shades

When Wearing Eyeglasses

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

prevent the eyeglasses from being scratched.

When Not Wearing Eyeglasses

Extend the folded eyeshades in the direction of the arrow to prevent

extraneous light from entering between the eyepieces and eyes.
