Abstract

PURPOSE:To enable branching characteristics to be changed without changing exit direction by so disposing an optical filter and a total reflecting mirror to cross with each other at the specified angle and making them rotatable so as to change the incident angle of light while maintaining said angle. CONSTITUTION:There are an optical filter F and total reflecting mirror M to a base 3 made of transparent material, the total reflecting mirror M being adjustable of its angle by a mounting screw 4. The point of intersection of the extension lines of the optical filter F and total reflecting mirror M is a shaft 2. As this shaft is turned by a knob 1, the incident angle to the optical filter F changes and branching characteristics change. However, the reflection direction of the total reflecting mirror M does not change. The light of the wavelength lambda1 transmits and the light of the wave length lambda2 is totally reflected. It is desired to change the lead-out position of the wavelength lambda2, only required is to change the angle of the total reflecting mirror M by means of the mounting screw 4.
