Aberration of light — Light from location 1 will appear to be coming from location 2 for a moving telescope due to the finite speed of light, a phenomenon known as the aberration of light. The aberration of light (also referred to as astronomical aberration or stellar … Wikipedia
aberration — aberrational, adj. /ab euh ray sheuhn/, n. 1. the act of departing from the right, normal, or usual course. 2. the act of deviating from the ordinary, usual, or normal type. 3. deviation from truth or moral rectitude. 4. mental irregularity or… … Universalium

Catadioptric system — A 150 mm aperture catadioptric telescope (Maksutov) A catadioptric optical system is one where refraction and reflection are combined in an optical system, usually via lenses (dioptrics) and curved mirrors (catoptrics). Catadioptric… … Wikipedia
Diffraction-limited system — Memorial to Ernst Karl Abbe, who approximated the diffraction limit of a microscope as , where d is the resolvable feature size, λ is the wavelength of light, n is the index of refraction of the medium being imaged in, and θ (depicted as α in the … Wikipedia
Reflecting telescope — 24 inch convertible Newtonian/Cassegrain reflecting telescope on display at the Franklin Institute. A reflecting telescope (also called a reflector) is an optical telescope which uses a single or combination of curved mirrors that reflect light… … Wikipedia

Korrektor (Teleskop) — Ein Korrektor ist eine spezielle Anordnung von Linsen oder Spiegeln, die Abbildungsfehler eines Fernrohrobjektivs vermindert oder Abbildungsfehler durch die atmosphärische Dispersion (chromatische Aberration) beseitigt. Es gibt verschiedene… … Deutsch Wikipedia
Strehl ratio — The modern definition of the Strehl ratio is the ratio of the observed peak intensity at the detection plane of a telescope or other imaging system from a point source compared to the theoretical maximum peak intensity of a perfect imaging system … Wikipedia
Tilt (optics) — In optics, the term tilt is a deviation in the direction a beam of light propagates. Tilt quantizes the average slope in both the X and Y directions of a wavefront or phase profile across the pupil of an optical system. In conjunction with Piston … Wikipedia
Piston (optics) — In optics, the term piston is the mean value of a wavefront or phase profile across the pupil of an optical system. The piston coefficient is typically expressed in wavelengths of light at a particular wavelength. Its main use is in curve fitting … Wikipedia
