Abstract

PURPOSE:To obtain an assembled optical system which has a lens array prescribed precisely, consists of less assembly constituent parts, excellent in mass- producibility, by providing numbers of lenses to a light shielding plate or by forming them by compression. CONSTITUTION:In a light shielding plate 3 which serves as a diaphragm for a visual field or the quantity of light, numbers of lenses 2 are set or formed by compression to prescribe the curvature, perpendicularity, etc., of a lens array 1 precisely. Further, the lenses 2 and diaphragm are formed in one body, so the number of parts constituting a lens assembly is decreased and assembling is facilitated. Therefore, a assembled optical system excellent in mass-producibility is obtained.
