Abstract
The coatings which are used on telescope mirrors and other optical interfaces can have a profound effect on the image quality formed by an optical system. This paper evaluates the defocus and astigmatism which are caused by the s- and p-phase shifts of coatings. These coating-induced wavefront aberrations are usually insignificant, but can, under certain circumstances, overshadow the geometric wavefront aberrations of the system. The wavefront aberrations induced by reflection-enhanced coatings on an f/1.5 Cassegrain telescope are numerically evaluated as an example.
