Installation Instructions
CS Mount Lenses
I Mechanical Construction.
Technical Specifications
The CS Mount lenses of the standard
series contain a so-called galvanometer
drive, i.e. on a moving-coil instrument
principle whereby the iris blades are
moved instead of the pointer.
The galvanometer is either driven directly
(variable DC voltage control) or by means
of a printed circuit amplifier (AI control)
in the lens.
AI control: Auto Iris
DC variable voltage control: DC Control
The C Mount pinhole lenses contain
a servometric iris drive, i.e. a moving-

magnet instrument system.
The video amplifier is built-in the lens.
Auto Iris models are driven - as usual - by
video signal, outside accessible potentio-
meters are used for „Level” and „ALC”
adjustments. The required control printed
circuit has to be integrated in the camera
if DC Control types are used.
Once the lens has been screwed onto the
camera, the slipping mechanism on the CS
Mount connection allows radial turning of
up to 350°, for example to locate the cable
connection at the desired point.
