IMAGING FILTER, CAPABLE OF LOWERING MANUFACTURING COSTS

摘要

PURPOSE: An imaging filter is provided to easily limit a light incident angle to an image sensor when using an image sensor by dividing a light receiving area in a very small area made of one or several pixels, thereby realizing a proper production number and making a mounting space of a thickness direction small.;CONSTITUTION: An imaging filter includes a transparent substrate, a light blocking film(42), and a reflecting film. The light blocking film is formed on a surface of a substrate. In the light blocking film, a plurality of openings(43) is formed at a uniform interval. The openings have a uniform size. The light blocking film blocks light incident on a part except the opening. The reflecting film is formed on a surface of a substrate. The reflecting film is made of a dielectric thin film of a multilayer. The reflecting film transmits light of a predetermined wavelength which is perpendicularly incident. The reflecting film reflects light of the predetermined wavelet which is diagonally incident.;COPYRIGHT KIPO 2010
