Optical Geometry Structure of Reflector Telescope
Keywords:
Astronomy, Optics, TelescopesAbstract
The field of physics that focuses on light is called optics, which investigates the properties of light, and how those properties are used. Geometric optics and physical optics are two branches of optics. Geometric optics study the refractive and reflective properties of light. Optika has produced a variety of tools that help human activity in certain fields. For example, in astronomy, stellar binoculars are used to observe objects in space. The purpose of this article is to show the development of the history of geometric optics and to study the definition, structure, working principle, disadvantages, and advantages of a reflector telescope or reflecting star binoculars. This method of writing articles uses qualitative methods and conducts literature searches on relevant articles, journals, and libraries. The result is that the reader knows the history, definition, structure, working principle, weaknesses, and advantages of the reflector telescope in geometric optics. The reflector telescope basically has 9 main parts, has 5 reflex media and 3 main components, namely the main mirror, the secondary mirror, and also the positive eyepiece so that the reflector telescope is created. This telescope itself has the main task, namely collecting, focusing, and magnifying light on an object.
