Abstract
Abstract An optical system of a television camera comprises, according to the invention, arranged in the direction of the light flux on one optical axis, an objective composed of n elements and a faceplate of a television tube, a light-sensitive layer being located on the last, in the direction of the light flux, surface of said faceplate. The last, in the direction of the light flux, element of the objective has an optical power other than zero and is made as, for example, a concave-flat lens having its concavity facing the object. This last element is the faceplate (3) of the television tube (4).
