<p>An optical system comprises, located consecutively along the direction of the light flux on one and the same optical axis (1), an objective (2) consisting of n components and a face plate (3) of the camera tube (4), on the last surface of which, along the light flux, a photosensitive layer (12) is provided. The last component of the objective (2), along the light flux, has a focal power different from zero, is made as a plano-concave lens and serves as the face plate (3) of the camera tube (4).</p> |
