The freeform surface might help to lessen the incident angle and exit angle of marginal ray to much more effectively harmony another aberrations. Herein, the main intention would be to confirm that a much better functionality might be attained with using a freeform lens in a very refractive IR optical method when compared with an aspheric lens.See … Read More
