NOT KNOWN FACTS ABOUT UNCOOLED LONG-WAVE INFRARED LENSES

Not known Facts About Uncooled Long-Wave Infrared lenses

The freeform surface may also help to decrease the incident angle and exit angle of marginal ray to more correctly stability one other aberrations. Herein, the principle purpose would be to validate that an improved performance will probably be accomplished with using a freeform lens in the refractive IR optical method as compared to an aspheric le
