摘要

PROBLEM TO BE SOLVED: To provide an optical filter including two transparent flat plates different in optical characteristics, in which a first transparent flat plate and a second transparent flat plate can be arranged and fixed to be orthogonal to each other.;SOLUTION: The optical filter including two transparent flat plates different in optical characteristics comprises: the first transparent flat plate having a first notch; and the second transparent flat plate having a second notch. The width of the first notch is equal to or more than the thickness of the second transparent flat plate and the width of the second notch is equal to or more than the thickness of the first transparent flat plate. The second transparent flat plate is inserted into the first notch and the first transparent flat plate is inserted into the second notch, so that the first transparent flat plate and the second transparent flat plate are arranged to be orthogonal to each other.;COPYRIGHT: (C)2014,JPO&INPIT
