Abstract

PURPOSE:To improve the contrast ratio of the output image of an optical image element by constituting said element of a composite insulating layer consisting of a single crystal plate and amorphous diamond films and transparent electrodes. CONSTITUTION:Thin films consisting of oxide such as silicon dioxide, zirconia, alumina or yttrium oxide are formed as protective films on the surfaces of the single crystal 1 and thereafter amorphous diamond films which are insulating layers 2,2' are deposited thereon. The transparent electrodes 3, 3' are provided on the surfaces of such thin films. The amorphous diamond films are formed by a plasma CVD method in gaseous methane flow. Since the substrate temp. is low in this case, the optically uniform films are obtd. without the oxygen deficiency on the surface of the single crystal by the dissipation of oxygen from bismuth silicon oxide which is the substrate or the generation of the exfoliation and cracking of the films by the difference in the coefft. of thermal expansion. Then contrast ratio of output image of the optical image element is thus improved.
