WHAT DOES UNCOOLED LONG-WAVE INFRARED LENSES MEAN?

The good news is, an NRFS involves considerably less optimization time than common freeform surfaces and is much more ideal for an FTS-processing manner of IR materials. From the research of this system, the freeform lens layout could be placed on additional complicated refractive IR imaging units.In some instances, I have sought out third-get toge
