| An optical telescope gathers and focuses light mainly from the visible part of the Electromagnetic spectrum. Optical telescopes increase the apparent angular size of distant objects, as well as their apparent brightness. Telescopes work by employing one or more curved optical elements - lenses or mirrors - to gather light or other electromagnetic radiation and bring that light or radiation to a focus, where the image can be observed, photographed or studied. There are three main types; Refracting telescope which uses solely an arrangement of lenses. Reflecting telescope which uses solely an arrangement of mirrors. Catadioptric telescope which uses a combination of mirrors and lenses. | ||
