Luminit Light Shaping Diffusers homogenize and directionally shape light with high transmission efficiency and excellent hiding power. Available in seamless rolls on polycarbonate, polyester or acrylic substrates, including UV-stable or UL-approved substrates, we offer diffusers with elliptic and circular outputs in a variety of substrates, sizes and angles from small to extreme. We can custom cut to your specifications, and offer low-cost Injection Molded (IM) lenses that can be designed in a variety of shapes and sizes in symmetrical and asymmetrical beam angles for any LED module design.
All LSD angles are specified in FWHM.
Large angle LSDs, when placed at the image plane, make excellent high resolution viewing screens.
Small angle LSDs can be combined with polarizers to reduce moiré and improve uniformity
LSDs can be combined with other optical components such as lenses, Fresnels, and prismatic structures.
Superior optical transmission between 300nm and 1500nm
Anti-reflective in nature
With LSD, transmission improves to 92%.
LSDs precisely shape, control and distribute light
Standard circular angles range from 0.5° to 100° FWHM.

Beam Shaping LSDs precisely shape, control, and distribute light. The patented holographic master recording process allows a variety of circular or elliptical light patterns. Standard circular angles range from 0.5° to 100° FWHM.
Homogenized Light “Hotspots” and uneven light distribution are common problems with filament, arc, LED, CCFL, fiberoptic, and laser light sources. LSDs greatly smooth and homogenize sources while providing uniform light in critical applications such as LCD backlights, LED displays, machine vision, automotive lighting, and viewing screens. Large angle LSDs produce the greatest degree of homogenized light.
