are each a prism, 1X, 1Y, 1Z are light exit surfaces,
1a1 is a light reflecting surface, 5 is a substrate, 6 is a support member, 6
a and 6b are support pieces, 7 and 9 are screws, 8 is a holding fitting, 10 is an adapter, and L is incident light.

Claims

[Scope of utility model registration request]

One end of the support member is applied directly or via a substrate with the incident surface side of a color separation prism having at least two prisms that reflect an incident light beam multiple times to separate the light beams into at least two or more color lights and emit them as a reference plane. A reflective surface or an exit surface of a prism that constitutes the color separation prism by support pieces that are supported in contact with each other and that are branched into at least two other ends of the support member, the tip portions of which are bent in different directions. 1. A support member for a color separation prism, wherein the support member is made of a material having a linear expansion coefficient substantially equal to a linear expansion coefficient of a prism constituting the color separation prism.
