Sensor Responsivity and Design

Responsivity

The responsivity graph illu strates the sensor's response to d ifferent w avelengths of light (exclud ing len s
and light source characteristics).
Note: The responsivity of a color camera w ill measure approxim ately 1/ 6
camera m od el as a resu lt of the effect the color filter has on the sensor and also d u e to the color camera
not incorp orating TDI Mod e.

Filters
CMOS cameras are responsive to infrared (IR) w avelengths of light. Infrared light can be problem atic
w ith halogen light sources but is not a issue w ith w hite LED sources. When infrared light is present w ith
this camera color fid elity is red uced . To prevent infrared from d istorting the images you scan, use an IR
cut off filter such as a BG-38 on the lens.
