The Cassegrain reflector is a combination of a primary concave mirror and a secondary convex mirror, often used in optical telescopes and radio antennas, the main characteristic being that the optical …

The meaning of CASSEGRAIN TELESCOPE is a reflecting telescope that has a paraboloidal primary mirror and hyperboloidal secondary mirror, is equivalent in its optical effects to a telephoto lens, and …

The design was proposed in 1672 by French priest Laurent Cassegrain. In the Cassegrain reflector, parallel rays of light entering the telescope are reflected from a large concave mirror toward the focal …

Due to the added difficulty of making strongly aspheric convex surface (hyperboloid) for the secondary, the Cassegrain was the last to come into efficient use, but soon became the most popular two-mirror …

Jun 4, 2024 · The Cassegrain, or Classical Cassegrain as it has become known, is a well-corrected, two mirror telescope that was developed by Laurent Cassegrain and is the foundational design of many …

Oct 21, 2023 · The Cassegrain reflector is designed to optimize light collection and enhance image clarity, making it particularly effective for observing deep-space phenomena. The Cassegrain is a …

Named after French mathematician and engineer Laurent Cassegrain, Cassegrain telescopes feature a unique optical design that distinguishes them from other types of telescopes like refractors and …

A Cassegrain telescope is traditionally a type of reflective telescope. However, it is often combined with refractive lens too, which can help to provide an even better view.
