Abstract

With the current retinal imaging systems, laser cavities and astronomical spectroscopes, there is the need to employ off-axis reflective systems. These systems, often used in configurations where the object or image are at the infinite with respect to the spherical mirrors, are the most used in this type of instrumentation. Expressions for the wavefront aberrations in an off-axis spherical mirror with image or object at the infinite are presented, analyzed and evaluated. Formulas are derived from the optical path difference between a paroboloid, as reference surface, and a sphere. Exact and approximate expressions, assuming a relative small pupil and a small angle of incidence are presented. They can be used to design and analyze some off-axis reflective systems.
