Lurie-Houghton Telescope
Design Equations

GRAPHIC: LH Design Equations
Here are the basic design equation for the Lurie-Houghton telescope. They calculate the radius of curvature for the corrector lens surfaces. You need to supply the index of refraction of the glass used for the corrector lenses, the focal length of the primary mirror, and the distance of the last lens surface to the reflection surface of the primary mirror along the optical axis.
