THE BEST SIDE OF UNCOOLED LONG-WAVE INFRARED LENS

Fortuitously, an NRFS requires less optimization time than standard freeform surfaces and is more suitable for an FTS-processing mode of IR resources. From the examine of This technique, the freeform lens layout could be placed on far more complicated refractive IR imaging units.This technique consists of four lenses. Only one diffractive lens on L
