LITTLE KNOWN FACTS ABOUT COOLED LONG-WAVE INFRARED LENS.

The distortion will speedily lower Using the reduce in FOV, and it is the reverse condition for giant FOVs as a result of 3rd-electricity relation among the distortion benefit and FOV angle. The edges in the impression are curved because the level of distortion may differ with the dice of the distance with the axis. As a result, the distortion of t
