WEBThe optical system, called the Optical Telescope Assembly (OTA), gives Hubble a unique view of the universe by gathering infrared, visible and ultraviolet light. The OTA is supported by a graphite epoxy skeleton.
Optical telescope - Wikipedia
WEBAn optical telescope is a telescope that gathers and focuses light mainly from the visible part of the electromagnetic spectrum, to create a magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors.
WEBShaping light into an image: first principles. A telescope must bend or reflect light rays to make them converge to a small (ideally smaller that the atmospheric seeing size for ground telescopes) zone in the focal plane. At optical/nearIR wavelengths, …
WEBThis paper discusses the optical design of the Origins Space Telescope. Origins is one of four large missions under study in preparation for the 2020 Decadal Survey in Astronomy and Astrophysics.
Hubble Design - Science@NASA
WEBThe Telescope Hubble is classified as a Cassegrain reflector, named after a 15th century French cleric who was among the first to suggest this basic optical design. Light hitting the telescope’s main, or primary, mirror is reflected to a smaller, secondary mirror suspended above the primary.
WEBLocation of focus & instrument(s) is key to telescope design. Telescopes are designed with instrument(s) in mind. Sometime, a specialized telescope + instrument are designed together. Subaru telescope (8.2m): location of the 4 telescope focii.
Telescopes 101 - NASA Science
WEBTelescopes Astronomers observe distant cosmic objects using telescopes that employ mirrors and lenses to gather and focus light. The size of the main mirror or lens determines how well a telescope can collect light.
