Use without Glasses
If you have visual impairments and wish to observe the sample without glasses, you
can adjust the eyepieces to compensate for the impairments:
Procedure
1
Ensure the left eyepiece is in the zero position.
The zero on the ring should be next to the white dot of the eyepiece.
2
Select a magnification between 10x and 20x.
3
Look at the sample through the left eyepiece with your left eye only.
4
Raise or lower the stage until the sample is in focus.
For more information, see Selecting Objectives and Focusing [
20].
5
Look at the sample through the right eyepiece with your right eye only.
6
Turn the right eyepiece ring until the sample is in focus.
A diopter scale on the ring also helps you find the correct setting.
The sample should now be in focus when you look at it with both eyes. Once you
have adjusted the eyepieces, you should subsequently only change the focus of a
sample by turning the focus wheel. For more information, see Selecting Objectives
