5 TIPS ABOUT UNCOOLED LONG-WAVE INFRARED LENS YOU CAN USE TODAY

The freeform surface area loses its rotational symmetry assets that needs more ray sampling in the entire process of optimization, which gives rise to some slower ray tracing composition and larger concurrency price than spherical and aspheric surfaces.This system consists of four lenses. Only one diffractive lens on L1 and a single conical surface
