Schmidt-Cassegrain Telescope
Abstract
The Schmidt-Cassegrain telescope is a very popular design for amateur astronomical telescopes for its high contrast and low aberration effects. It consists of a Schmidt corrector plate and a Cassegrain reflector. The Cassegrain reflector is made up of a concave primary mirror for focusing the light and a convex secondary mirror that redirects the light back through a hole in the primary. This provides a long focal length even with a short tube length. The Schmidt plate itself is an aspherical lens used to correct spherical aberrations.

Wavefront Error Detector
Wavefront error is defined as the difference between the reference wavefront phase, which is a constant phase or spherical phase, and the detected wavefront phase of one optical system.
