When to use C-mount Adapter with IR-cut Filter
Use of C-mount adapter with IR-cut filter with the color cameras
Since the SMX-10Mx color cameras are sensitive to IR-light, use the C-mount adapter
with IR-cut filter for the color camera models to make colors of the image more
realistic.
Some light sources, including the sun, emit infrared light, so the color camera in
daylight will see a significant amount of infrared light without the
IR-cut filter . As a
result, non-realistic colors appear.
Another reason for using the IR-cut filter is the limited color correction for some lenses.
that have different depth of focus for the visible and infrared spectrum. The IR-cut filter
cuts 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 sensor). This is primarily due to the
IR-cut filter .
