LN 692 is a lenticular optic designed for light management in applications such as projection screens and 3D images. It has a clear aperture of 230.2 x 180.0 mm², a lenticular length of 180.0 mm, a facet spacing of 0.162 mm, and a radius of 0.762 mm, with a standard thickness of 1.8 mm. The material is PMMA with a refractive index of 1.49.
Lenticulars have linear structures where every groove has a small radius creating multiple line images. They are primarily used for projection screens and three dimensional images.
The designs can be trimmed according to customer requirements (within limits of clear aperture). Optical coatings for increased efficiency are possible.
