Introduction
The spectral response for the A202
Figure 1-2: A202
The spectral response curve excludes lens characteristics and light source
characteristics.
To obtain best performance regarding the camera's blooming, smearing and dark
signal non-uniformity characteristics, use of a dielectric IR cut-off filter is
recommended. The filter should transmit in a range of 400 nm to 700...720 nm, and
it should cut off from 700...720 nm to 1100 nm.
A suitable filter is included in the C-mount adapter.
The F-mount adapter does not include the filter. A suitable filter type is the B+W486,
for example.

cut filter as standard equipment. The filter is mounted in the lens adapter. The
location of the filter limits the thread length of the lens that can be used on the
camera. The thread length on your lens must be less than 7.5 mm. If a lens with
a longer thread length is used, the camera will be damaged and will no longer
operate. See Section 5.5
Cameras without an IR cut filter in the C-mount lens adapter are available on re-
quest.
