Abstract

PURPOSE:To improve the resolusion of an image sensor by applying reflection preventing coating to the surface of a transparent protecting layer to reduce invalid light. CONSTITUTION:A light-shielding layer 7 is applied to the surface of a transparent substrate 6 such as glass except a transparent window 13 and the array of photoelectric conversion elements 8 using photoconductive materials such as CdS and Se is formed on the surface of the light-sheilding layer 7. A transparent electrode 12 is formed on one side of the photoelectric conversion elements 8 and an opaque electrode 9 such as Al and InSn is formed on the other side. Adherent 14 such as silicone resin and lens bond is applied to the surface of the elements 8, a thin glass plate 15 is fitted to the surface of the adherent and a single layer relfection preventing film 16 is applied to the surface of the thin glass plate 15 by vacuum evapolating or sputtering a material with low refractive index such as magnesium fluoride (MgF2) and rock crystal (3NaF.AlF2). When the thickness, refractive index of the single layer reflection preventing film 16 and the wavelength of incident light flux 10 are d, n and lambda respectively, the thickness of the single layer reflection preventing film 16 is determined so that nd lambda/4 is satisfied.
