Paper Abstract

Compensation method is a popular method for testing aspheric surface. In this dissertation, a compensator is designed according to normal aberration compensation method. In order to realize the normals of emergent wavefront of compensator consistent with that of aspheric surface, the concept of virtual glass is adopted. According to the characteristic of aspheric surfaces, general method of determining virtual glass model's parameters in ZEMAX is presented. Single pass layout using virtual glass model for designing compensator is proposed. It reduces the number of surfaces by a half. This simplifies the process of design and optimization and improves the accuracy of design. A design example is given. The maximum optical path difference is less than 0.0001λ(λ=632.8 nm).
