How to Evaluate Camera Sensitivity | Teledyne FLIR

+

Mar 17, 2021· The graph shows that absolute sensitivity threshold (the light level at which signal is equal to the noise) is reached by the ½’’ sensor at a slightly lower level than that of ¼’’ sensor. The more important measure needed to determine which camera will perform better in low light applications is the signal to noise ratio (SNR).

Are digital sensors sensitive to UV? Photography Stack ...

+

Unfiltered, a digital sensor is sensitive to a far greater range, from deep UV (200nm, true UV) down to true IR (as far as 900nm) [1]. It should be noted that sensitivity is not constant throughout this range, and falloff is fairly rapid and becomes significant the farther away from 380nm you go. Same goes for the IR range.
