HOW MUCH YOU NEED TO EXPECT YOU'LL PAY FOR A GOOD UNCOOLED LONG-WAVE INFRARED LENS

The freeform area will help to decrease the incident angle and exit angle of marginal ray to more correctly balance one other aberrations. Herein, the primary objective is always to confirm that an improved efficiency is going to be reached with the usage of a freeform lens in the refractive IR optical technique in comparison with an aspheric lens.
