Abstract
Optical design for fish-eye lenses usually includes a front meniscus lens that reduces the angles of incidence of chief rays towards the rest of the optics. However it also introduces distortion of the pupil, both shape and position. Thus, pupil aberration are one of the most relevant problems when designing this type of lenses. This paper shows the relationships between image and pupil aberrations and describes the design of MWIR fish-eye lenses that include diffractive surfaces in order to properly control entrance pupil size. The design goal is to achieve a constant pupil area over the field of view.
