Filters in Alvium USB color cameras
C-Mount and CS-Mount models of Alvium USB color models are delivered with IR
cut filter. The filter is permanently installed and cannot be removed.
Monochrome and S-Mount models are delivered without filter. This extends the
sensitivity for low-light imaging. Moreover, spectral sensitivity is increased. As a side
effect, color, contrast, and sharpness can be affected by near-IR wavelengths.
NOTICE
Damage to sensor or optics by unsuitable lenses
The sensor, filter, or lens can be damaged if a lens exceeding maximum protrusion
is mounted to the camera.
