Abstract
In the current retinal imaging systems, laser cavities or astronomical spectroscopes, there is the need to employ off-axis reflective systems. These systems often use different configuration where the object or image could be at finite distances or at infinity with respect to the spherical mirrors. In this work, expressions for the wavefront aberrations in an off-axis spherical mirror with image point or object point from different cases are presented, analyzed and evaluated. Assuming a relatively small pupil and a small angle of incidence, these formulas are derived from the optical path difference between a reference surface (paraboloid, ellipsoid or hyperboloid), and a sphere. They can be used to design and analyze some off-axis reflective systems.
