Glass Rhomboid prism off-set prism

Rhomboid Glass Prism are commonly used to displace a laser beam without changing its direction. In imaging applications, rhomboid prism will displace the optical axis without inverting the image. The lateral displacement is equal to the length of the prism (specified by dimension D). Our Rhomboid Prism feature high tolerance angles that keep the output beam parallel to the input beam to within 30 arc seconds. Rhomboid prism are ideal for demanding displacement applications. 

They maybe coated to transmit part of the beam and produce two parallel and displaced emerging beams. Rhomboid prism can be coated to produce a polarizing beam separator. Dimension and coating are available by custom orders.

Besides the rhomboid prism, other types optical glass prism, such as Right Angle Prism,Penta Prism,Corner Cube Prism, Dove prism, corner cube prism,Bauernfeind prism,Roof Prism etc. Please contact us request for quotation.
