PROCESS OF FORMING A LIGHT BEAM PATH IN A DIELECTRIC MIRROR
First Claim
1. An optical mirror element, comprising:
- an optically transmissive element having a first surface and a second surface;
a reflective coating on the first surface that defines a mirror surface, wherein a first portion of the first surface does not include said reflective coating layer such that the first portion defines an optically transmissive window in the mirror surface.

Abstract
An optical mirror element includes an optically transmissive element having a first surface and a second surface, and a reflective coating layer on the first surface that defines a mirror surface. A first portion of the first surface does not include the reflective coating layer such that the first portion defines an optically transmissive window in the mirror surface. Q method of forming an optical mirror element having a window portion includes providing an optical element, masking a first portion of a first surface of the optical element, and thereafter applying a reflective coating to the first surface so as to define a reflective surface, wherein the masked portion defines a transmissive region in the reflective surface. The exposed portion of the first surface may be coated with an anti-reflective coating, either before or after the reflective coating is applied.
