Abstract:
In an embodiment, an optical component is provided. The optical component includes a first polarizing prism having a first face, a second face and a third face. The light beam may be received incident on the first face. Light having a first polarization may be output through a second face and light having a second polarization may be output through a third face. The optical component further includes a half-wave plate fastened to the second face of the first polarizing prism. The optical component further includes a first reflecting prism connected to the third face of the first polarizing prism. The first reflecting prism has a first face and a second face, the first face connected to the third face of the first polarizing prism. The optical component further includes a second reflecting prism connected to the half-wave plate and to the second face of the first reflecting prism. The second reflecting prism has a first face, a second face and a third face. The first face of the second reflecting prism connected to the half-wave plate and the second face of the first reflecting prism. The optical component may be used in a projector, among other potential applications in some embodiments.
