The correct interpupillary distance

The interpupillary distance is correctly set if you see a single circular image field when looking at a specimen.

If you are still a novice microscope user, you may need a short time to become accustomed to this. Not to worry—after a little while, it will become automatic.

Reference values

The distance between eye and eyepiece measures approx. 22 mm for 10/23B widefield eyepieces for persons wearing glasses.

Adjusting the interpupillary distance

1.Look into the eyepieces.

2.Hold the eyepieces with both hands. Push the eyepieces together or separate them until you see a circular image.

3.Slowly approach the eyepieces with your eyes until you can see the complete image field without corner cutting.
