the difference in sensitivity is significant. This is important to know since
many light sources, including the sun, emit infrared light. A CCD color camera
in daylight without an IR-cut filter will therefore see a significant amount
of infrared light resulting in strange colors. Another reason for using an IR-cut
filter is the limited color correction for many lenses. It is difficult to design
imaging optics covering both the visible spectrum and the near infrared spectrum
at the same time. Therefore, many lenses have different depth of focus for the
visible and the infrared spectrum. Anyway, the IR-cut filter cuts away a significant
amount of the overall collected light and thereby affects the sensitivity in
a negative way. In general, color cameras are one factor less sensitive compared
to monochrome (depending on the CCD chip). This is primarily due to the IR-cut
filter. [Info courtesy of Jai Camera Solutions]
