Color Camera Spectral Response

The following graphs show the spectral response for each available color camera model
The spectral response curves exclude lens characteristics, light source
characteristics, and IR-cut filter characteristics.
To obtain best performance from color models of the camera, use of a dielectric
IR cut filter is recommended. The filter should transmit in a range from 400 nm to
700 ... 720 nm, and it should cut off from 700 ... 720 nm to 1100 nm.
A suitable IR cut filter is built into the cylindric housing extension in color models
of the camera.
