Vertical tube adapters
When attaching photomicrographic equipment or TV camera to the vertical tube of the trinocular
eyepiece tube, you must first mount the adapter (photomicrographic vertical tube adapter or direct
C-mount adapter; both sold separately). Insert the adapter into the vertical tube and secure it with
the clamp screw using a hexagonal screwdriver.
Angular adjustment of binocular part (for the LV-TT2 only)
With the trinocular eyepiece tube LV-TT2, the angle of
the binocular part can be adjusted. Adjust it to an easily
viewable angle.
Centering the binocular part (for the LV-TT2 only)
The binocular part and the vertical tube part of the eyepiece
tube are centered before the shipping, so usually they can be
used with no adjustment.
But some cameras are not aligned their centers of the CCD
to the mount. You can center the vertical part by adjusting
two centering screws on the back of the vertical tube for
such cameras.
