Adaption
Various adapters are available for the
connection of TV cameras with c-mount and B-
mount thread (Fig. 43).
The c-mount adapters listed in the following
table can be used on all trinocular phototubes.
Some tubes (Figs. 43 – 45) require a photo
adapter tube as well. The picture area on the
monitor depends on the adapter used and on the
chip size of the camera.
Calculation of the magnification on the monitor
The magnification on the monitor M
TV
can be
calculated with the following formula or
measured with a stage micrometer and a cm
scale:
M
TV
= objective magnification x
factor of magnification changer* x
TV adapter magnification x
monitor diameter
chip diameter of camera
