Schmidt camera optical axis of the Schmidt design creates a Schmidt-Newtonian telescope. The addition of a convex secondary mirror to the Schmidt design directing light through a hole in the primary mirror creates a Schmidt-Cassegrain telescope. The last two designs are popular with telescope manufacturers because they are compact and use simple spherical optics. A short list of notable and/or large aperture Schmidt cameras. 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
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.
