THE 2-MINUTE RULE FOR UNCOOLED LONG-WAVE INFRARED LENS

The freeform surface will help to lessen the incident angle and exit angle of marginal ray to additional correctly equilibrium the other aberrations. Herein, the leading aim is always to verify that a better effectiveness will be achieved with the use of a freeform lens in a refractive IR optical procedure in comparison with an aspheric lens.The co
