Optical beamsplitter
First Claim
1. An optical module including a beamsplitter comprising a body having two major surfaces, at least one major surface of the body being coated so that the said major surface reflects a first portion of incident light of a desired wavelength which is primarily a first polarization, and the other major surface reflects a second portion of the incident light of the desired wavelength which is primarily an orthogonal polarization with respect to the first polarization while transmitting a remaining portion of the incident light without the body substantially changing the polarization of the light as it passes through the body.

Abstract
The invention is a beamsplitter and an optical module including a beamsplitter where the beamsplitter comprising a body having two major surfaces. At least one major surface of the body is coated so that the said major surface reflects incident light of a desired wavelength which is primarily a first polarization. The other major surface reflects incident light of the desired wavelength which is primarily an orthogonal polarization without the element substantially changing the polarization of the light as it passes through the element.
