Abstract

PURPOSE:To enable the use of an iris diaphragm in the regulation of the quantity of light by setting a half mirror in front of a concave mirror in an oblique state to the optical axis. CONSTITUTION:Incident luminous fluxes are passed through a half mirror 2, reflected by a concave mirror 1, further reflected by the mirror 2, passed through a hole 4 for taking out luminous fluxes, and subjected to the regulation of the quantity of light with an iris diaphragm 3 to form an image on an image forming surface 5. To reduce the telephoto ratio the mirror 2 is made convex. Since the luminous fluxes used to form the image are circular in cross- section, the iris diaphragm can be used in the regulation of the quantity of light.
