Eyepieces
Using a binocular (or trinocular) tube is less tiring for the eyes than a monocular tube. In order to
obtain a smooth “compound” image, we recommend you to go through the below steps.
1. The interpupillary distance
The correct interpupillary distance is reached when one round image is seen in the field of view
(see image below). This distance can be set either pulling the tubes towards each other or pulling
them away from each other. This distance is different for each observer and thus should be set
individually. When more users are working with the microscope it is recommended to remember
your interpupillary distance for a quick set up during new microscopy sessions. The MT - 420 and
MT - 430 swiveling eyepiece tube can be rotated 360º. You can select corresponding eye point
height according to your own preference.
2. The correct eye point
The eye point is the distance from the eyepiece to the user’s pupil. To obtain the correct eye point,
move the eyes towards the eyepieces until a sharp image is reached at a full field view.
