Operation for the Aperture Diaphragm for the Episcopic Illumination
When the LV-UEPI2A epi illuminator is connected with this product, the A.S. indicator lights up.
The aperture diaphragm in the LV-UEPI2A can be adjusted by operating the A.S. control buttons.
Since the aperture diaphragm is used for adjusting the numerical aperture of the illumination
system, this diaphragm is related to the resolution, contrast, and depth of focus of the optical image.
Operation for the aperture diaphragm for the episcopic illumination
To adjust the aperture diaphragm, operate the open/close
button of the A.S. controls.
When the aperture diaphragm is set to the maximum or
minimum size and its size is attempted to be changed
farther, a beep sounds.
To adjust the aperture diaphragm, remove one of the
eyepieces, and then adjust the aperture diaphragm opening
to 70 to 80% of the pupil of the objective while observing
the pupil of the objective (the bright area when the
aperture diaphragm is fully opened) in the eyepiece tube.
Interlock function
When the interlock function is enabled with “LVSetup”,
the aperture diaphragm opening for the episcopic
illumination is controlled to the predetermined condition
in conjunction with the microscopy method or with the
objective.
If the aperture diaphragm for the episcopic illumination is
changed after the interlock function, the A.S. indicator
blinks to notify it.
