Abstract

A new optical surface, Virtual Normal Surface (VNS) model is constructed in concept. With the special surface type, a lens in double-pass can be turned into single pass configuration in optical software, which makes the modeling the optical system easier. The VNS is realized in optical software ZEMAX. The normal aberration of an aspheric surface is simulated and visualized in ZEMAX with the VNS. VNS can also be used in modeling null corrector, which makes optimizing, applying constraints to lens data, and tolerance analysis more quickly and easier.
