The PR 709 is a Fresnel prism designed to deflect collimated light at a 10° angle with a facet spacing of 1.016 mm. It has a clear aperture of 216.6 x 216.6 mm², a prism length of 216.6 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. Outside dimensions may exceed the clear aperture by up to 20 mm. Special designs and thicknesses down to 0.8 mm can be requested.
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.
