90° Deviation of Beam or Image

Produces Inverted Image

Material: N-BK7, Grade A Fine Anneal

Surface Flatness: λ/10

Roof Prism is made from N-BK7, an RoHS compliant version of BK7, and can be used when a right angle deflection of an image or laser beam is required. In passing through the prism, the image is both deflected right-to-left and top-to-bottom. The hypotenuse of the prism utilizes total internal reflection (TIR) to reflect the image through the prism. Polarization states may become rotated during reflection.
