What is "schmidt"

type of astronomical telescope lens used for photography, 1939, from Estonian-born German optician Bernhard Voldemar Schmidt (1879-1935), who invented it.

Schmidt is a small lunar impact crater that is located near the southwest edge of Mare Tranquillitatis, to the southwest of the Ritter– Sabine crater pair. This formation is circular and bowl-shaped, with little appearance of wear due to subsequent impacts. The interior has a higher albedo than the surrounding terrain, giving it a light appearance. The exterior consists of hummocky terrain with many boulders, ranging up to 100 m or more in diameter.

Schmidt is a common German occupational surname derived from the German word "Schmied" meaning "blacksmith" and/or "metalworker". This surname is the German equivalent of "Smith" in the English-speaking world.
