® light shaping diffusers Technical Data Sheet Holographic Light Shaping Diffusers® or LSD® are holographically recorded, randomized surface structures which enable: High Transmission Efficiency - 92% Luminit’s holographic Light Shaping Diffusers offer superior optical transmission between 300nm and 1500nm. Depending on the angle of distribution, LSDs will achieve between 85% and 92% transmission efficiency. 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%. Note: Luminit measures transmission utilizing an integrated sphere with the LSD structure facing the light source. Listed are the transmission efficiencies of a 10° LSD measured at the following wavelengths: 532nm-90%, 632nm-90%, 850nm-89%, 980nm-89%, 1064nm-89%, 1550nm-88% (UV Transmitting Diffusers are also available). 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 80° FWHM.
