Sensor Responsivity and Design
Responsivity
The resp onsivity grap h illu strates the sensor‘s resp onse to d ifferent w avelengths of light (exclu d ing len s
and light sou rce characteristics).
Note
: The resp onsivity of a color cam era w ill m easu re ap p roxim ately 1/ 6
th
that of a sim ilar m onochrom e
cam era 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 cam era
not incorp orating TDI Mod e.

Filters
CMOS cam eras are resp onsive to infrared (IR) w avelengths of light. Infrared light can be p roblem atic
w ith halogen light sou rces bu t is not a issu e w ith w hite LED sou rces. When infrared light is p resent w ith
this cam era color fid elity is red u ced . To p revent infrared from d istorting the im ages you scan, u se an IR
cu t off filter su ch as a BG-38 on the lens.
