Description
Optical 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 luminit diffuser films 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.
Benefits
- 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.
Features
- Provide precise beam control
- Eliminate striations and beam non-uniformity
- Supply direct view homogenization
