PR 727 is a fresnel prism designed to deflect collimated light with a 5° deflection angle and a facet spacing of 0.508 mm. It has a clear aperture of 303.7 × 164.4 mm², a prism length of 303.7 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, and other materials or thicknesses ≥0.8 mm are available upon request. Dimensions may extend up to 5-20 mm beyond the clear aperture, and custom trimmings are possible.
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.
