Schmidt camera Schmidt camera A Schmidt camera, also referred to as the Schmidt telescope, is a catadioptric astrophotographic telescope designed to provide wide fields of view with limited aberrations. The design was invented by Bernhard Schmidt in 1930. Some notable examples are the Samuel Oschin telescope (formerly Palomar Schmidt), the UK Schmidt Telescope and the ESO Schmidt; these provided the major source of all-sky photographic imaging from 1950 until 2000, when electronic detectors took over. A recent example is the Kepler spacecraft exoplanet finder. Other related designs are the Wright Camera and Lurie–Houghton telescope. The Schmidt camera was invented by German-Estonian optician
Alexander Schmidt (physiologist) life. From 1885 to 1889 he served as university rector. Schmidt is remembered for his research involving the process of blood coagulation by demonstrating that the transformation of fibrinogen into fibrin was the result of an enzymatic process. He named the hypothetical enzyme "thrombin", and he called its precursor "prothrombin". Schmidt is credited for providing a foundation for the creation of anti-coagulation systems and towards the development of blood transfusion. Alexander Schmidt (physiologist) Hermann Adolf Alexander Schmidt (1831 – 22 April 1894) was a Baltic German physiologist from what was then the Governorate of Livonia in the Russian Empire. He
