Coupletech offers Beamsplitter Penta Prisms, which is one kind of Optical Elements. By adding a wedge and with partial reflective coating on first reflective surface, Optical prisms Beam splitter Penta Prisms can be used as Beamsplitter. We supply Beamsplitter Penta Prism with wedge and standard Transmission/reflection (T/R) ratio of 20/80, 50/50. Other T/R ratio is available upon request. Except Polarizing Beam Splitter Penta Prisms, Coupletech also offers Corner Cube Retro-Reflectors have three mutually perpendicular surfaces and a hypotenuse face.
Corner Cube Retro-reflectors operates on the principle of total internal reflection (TIR). A beam entering the effective aperture is reflected by the three roof surfaces and emerges from the entrance/exit surface parallel to itself. This property is independent of orientation of the retro-reflector, within acceptance angle limitations. For applications in which either the acceptance angle for TIR is exceeded, or the reflecting surfaces can not be kept sufficiently clean for TIR, a metal or dielectric coating can be applied to the reflecting surfaces.
