Abstract
A compound prism including a plurality of unit prisms which have reflective interfaces defined by outer and/or inner surfaces thereof and which are arranged so that light is reflected by an inner surface of the interface of one of the unit prisms and by an outer surface of the interface of another unit prism.
Claims32
A reflecting device comprising at least one mirror body having a reflecting surface, and at least one prism body having interfaces, said mirror body reflecting surface and said prism body interfaces including a convexity or concavity of the order of a laser wavelength, wherein a light beam, reflected by said mirror body reflecting surface, is reflected by an interface of said prism body interfaces.
A reflecting device comprising at least one mirror body having a reflecting surface, and at least one prism body having interfaces, said mirror body reflecting surface and said prism body interfaces including a convexity or concavity of the order of a laser wavelength, wherein a light beam, reflected by said mirror body reflecting surface, passes through a prism body interface closest to said mirror body surface, and is reflected by another prism body interface.
A reflecting device comprising at least one mirror body having a reflecting surface, and at least one prism body having interfaces, said mirror body reflecting surface and said prism body interfaces including a convexity or concavity of the order of a laser wavelength, wherein a light beam, reflected by said mirror body reflecting surface, passes through a prism body interface closest to said mirror body surface, and is reflected by another prism body interface, wherein one interface, of said prism body interfaces, comprises means for receiving an incident light beam, and another interface, of said prism body interfaces, comprises means for emitting a light beam from said prism body, said light beam being a polarized light beam.
