Optical components are simple optical elements that are used in the construction of optical systems. Based on their interaction with incident light, optical components can be divided into two categories: transmissive optical components, through which light passes, and reflective optical components, on which the light bounced back. Transmissive optical components include lenses, primes, windows, filters, etc. and reflective optical components include mirrors and retroreflectors. They are widely used in variety optical system including telescopes, microscopes, detectors, cameras, projectors, high power lasers, etc.
