PR 723 is a Fresnel prism designed to deflect collimated light with a 12° deflection angle and a facet spacing of 0.152 mm. It has a clear aperture of 165.2 x 165.2 mm², a prism length of 165.2 mm, and a standard thickness of 1.8 mm. The prism is made from PMMA with a refractive index of 1.49 and relative dispersion of 58, though other materials are available. Dimensions may extend up to 5-20 mm beyond the clear aperture upon request.
A Fresnel Prism has a linear structure with a constant prism angle. It deflects collimated light with a constant deflection angle.
The designs can be trimmed according to customer requirements (within limits of clear aperture). Optical coatings for increased efficiency are possible.
