LN 676 is a lenticular optic engineered to manage light, with a radius of 1.118 mm, facet spacing of 0.559 mm, clear aperture of 432.0 x 429.1 mm², lenticular length of 429.1 mm, and thickness of 2.5 mm. It is made from PMMA with a refractive index of 1.49 and relative dispersion of 58. The dimensions are consistent with the series, and other thicknesses down to 0.8 mm are available upon request.
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.
