Chapter 3 Operation Details
Eyelevel risers can be used to adjust the height of the
eyepiece tube for the user's eye point. Up to two
eyelevel risers can be attached in piles. When one
eyelevel riser is attached, the eyepiece height rises
25 mm.
Eyelevel riser
If you look through the objective that is 10X or
less than 10X when two eyelevel risers are
attached on the microscope, the rim of the
view-filed may look different from the one without
an eyelevel riser due to reduction of light
intensity.
Before adjusting the interpupillary distance, follow the
procedure described in "2.1 Bright-field Microscopy
under the Episcopic Illumination" or "2.6 Bright-field
Microscopy under the Diascopic Illumination," and
focus on the sample with the 10X objective.
Look through the eyepieces and adjust the binocular
part until the view fields for the right and left eyes
coincide.
This will facilitate the observation with both eyes.
The binocular part has a scale for interpupillary
distance. It is recommended to memorize or record
your interpupillary distance, so that the distance
between the eyepieces can be readily adjusted next
time.
