Abstract

PURPOSE: To enable one element to detect two kinds of rays separately by forming the detection layer for the 2nd incident ray with short wavelength on the ray-striking surface of the substrate where the 1st incident ray with long wavelength among incident rays penetrates and by providing the detection layer for the 1st incident ray to the other surface of the substrate.
