Optical Dove prism

There are many types of prism, each having a particular geometry to achieve the reflections necessary to perform a specific imaging task. Reflecting prisms may invert, rotate, deviate or displace a beam. Dispersing prisms produce spectral separation for spectroscopic applications or for tuning a laser output. UPT provides many kinds of high precision prisms, including Penta Prism, Beamsplitter Penta Prism, Right Angle Prism, and Corner Cube. Our micro Penta Prism and Right Angle Prism are widely used in optical communication, such as optical switches. Other kinds of prisms, such as Dove Prism and Roof Prism are also available upon request. Penta prism can deviate an incident beam without inverting or reversing to 90°.The deviation angle of 90° is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. The reflecting surfaces of this Prism must be coated with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum or enhanced aluminum. By adding a wedge and with partial reflective coating on first reflective surface, Penta Prism can be used as Beamsplitter.We supply Beamsplitter Penta Prism with standard Transmission/reflection (T/R) ratio of 10/90,50/50.Other T/R ratio is available upon request.
