Abstract

A projection apparatus, comprising a fiber-optical plate (1), the entrance faces (2) of the light guides (3) of which coincide with the plane (a-a) of the image of the original, and a projection objective (8), the exit faces (9) of the light guides (3) of the fiber-optical plate (1) being disposed in the field of view thereof. An optical system (10) for concentrating the light rays into a light beam and directing that light beam into the entrance pupil (11) of the projection objective (8) is formed along the path of propagation of the light rays in each of the light guides (3) of the fiber-optical plate (1). The optical system (10) is formed by a focon (12), positive lens (13) and refracting prism (14), disposed successively along the path of the light rays in the light guide (3), while the optical axis (O3-O3) of the focon (12) and the optical axis (O4-O4) of the positive lens coincide with the optical axis (O1-O1) of the light guide (3).
