Responsivity & QE
The responsivity graph describes the camera‘s response to different wavelengths of light (excluding
lens and light source characteristics).
The image sensor includes micro lenses to improve the collection efficiency of the active pixel area.
The drawback to this is that the light collected varies with the angle of incidence, as shown in the
Angle of Incidence figure, below. Pixel Response Non Uniformity (PRNU) can be calibrated in the
field and takes into account the lighting and lens effects, and results in a more uniform output
level.
