Filter and lenses
IR cut filter: spectral transmission
The following illustration shows the spectral transmission of the IR cut filter.
Camera lenses
Allied Vision offers different lenses from a variety of manufacturers. The
following table lists selected image formats in width × height depending on
camera type, distance and the focal length of the lens.

(type Hoya C5000)
Note
All calculations apply to the principle planes of the lenses:
these are unknown (real lenses are not infinite thin).
All calculations are valid only for a distortion free optical
image (among other things: not valid for fisheye lenses).
