IR cut filter
By default, C-Mount and CS-Mount models of Alvium USB color models are
delivered with an IR cut filter. The filter is employed to prevent infrared light from
passing to the sensor. Without an IR cut filter, color reproduction quality can be
affected and images may be blurred, depending on scene illumination. See
for the filter transmission response.
Monochrome and S-Mount camera models are delivered without filter.
Spectral transmission values
Values may vary slightly by filter lot.

S-Mount lenses with IR cut design
For improved image quality, we recommend using S-Mount lenses that are
IR- optimized or that have IR cut coating. See the
