Definitions for "Spectral Response"
The sensitivity of the imaging device to different frequencies of light. This is usually in the range of 300-1000 nanometres. Visible light is up to 730nm, dull red infrared lighting from 700-850nm, invisible infrared is over 850nm.
is the sensitivity of a device to different light frequencies.
Sensitivity of an imaging device to different frequencies of light
Characteristic patterns of radiation reflected or emitted from an object; or, the ability of a sensing system to respond to radiation measurements within a spectral band.
The relative amplitude of the response of a detector versus the frequency of incident electromagnetic radiation. [NOAA
