1.4 Lens selection
Protection classes IP65 and IP67 can be fulfilled only in com­
bination with the protective tubing (see section A.4 Technical
data).
Lens dimensions when the
protective tubing is used Please observe the following if you wish to use the protect­
ive tubing:
– The maximum possible lens diameter is 38 mm
– The maximum possible length of the lens from the front
edge of the lens to the flange surface of the thread side is
42 mm.
Observe that with most lenses the lens length changes when
the focal position is reset. The setting “infinite” usually leads
to the shortest lens dimension.
Operation without protect­
ive tubing If you do not wish to use the protective tubing, you can use
lenses in accordance with the CS-mount standard.
If you use C-mount lenses without protective tubing, you
must screw in a 5 mm spacer ring in place of the protective
tubing, in order to guarantee correct support dimensions
(accessories see A.2).
