What are catadioptic telescopes?
Catadiopric telescopes are optical tools that discourage incoming images from the mirrors in the binoculars to increase the focal length and tool enlargement. This optical system creating an image has also been applied to other devices such as microscopes and photographic telephoto lenses. Comparable quality and capacity can be obtained with modern models for almost half of the cost and the third size compared to equivalent models made only of glass lenses. It is a particularly popular choice for amateur astronomers.
as a light reflecting or emitted by a remote object, entering the telescope, the system of convex and concave glass lenses called dioptrics bends light to affect the mirror mirror near the rear of the range. The mirror reflects the light back from the binoculars. It is then captured by another small circular mirror built near the front of the range, which re -reflects it with the center opening of the rear mirror. The use of such curved mirrors toDirect light is called catopter. Catadioptric telescopes are refractive or bending, light with glass lenses and discourage or redirect light with mirrored surfaces.
Light manipulation has been practiced in this way for a long time, but accurate applications began to be invented in the early 19th century. The earliest catadio -telescopes were called dialytes for their use of more glass lenses to repair some natural aberrations of light when lifting with crystalline structures. In 1876, the French engineer improved about it and invented the namesake "MANGIN MIRROR", who takes a glass lens with a silver mirror to correct for reflective light aberrations.
Subsequent improvement solved design efficiency, minimize obstacles from the path of light and other technical problems. Most of the efforts to improvisacis were to correct one type of light aberration or the other withoutHe resorted to an inefficient drug to add another element of glass diopters. One of the most popular commercial designs of Cathadiopian telescopes is called Schmidt-Cassegrain.
In this type of binoculars, light reflects and passes through the telescope before it gets into a single focus. The telescope with a line of focus would have to be three times as long and conical shape. It would be difficult and expensive with all the exact glass needed to maintain the integrity of the light rays. On the other hand, catadio -telescopes are compact rollers with a large diameter. Heavy glass is minimized and replaced by thin cheap sheets of silver mirrors polished for high accuracy.
