LITTLE KNOWN FACTS ABOUT COOLED LONG-WAVE INFRARED LENSES.

The distortion will swiftly reduce Using the decrease in FOV, and it's the reverse condition for giant FOVs due to third-electric power relation amongst the distortion price and FOV angle. The sides from the image are curved mainly because the quantity of distortion varies While using the cube of the distance from the axis. Hence, the distortion on
