Luminit 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 products with elliptic and circular outputs in a variety of substrates, sizes, and angles from small to extreme.
The low back-scatter of LSD structures are anti-reflective in
nature and utilize light that would otherwise be wasted due to Fresnel
loss. A clear piece of polycarbonate substrate is 89% transmissive.
With LSD, transmission improves to 92%.
We can custom cut light shaping diffusers 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.

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.
“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.
