ConstructionPhysical PropertiesChemical Resistance
Product TypesThickness & SizesOptical Data



 

CLAREX® DR-IIIS DIFFUSION FILTER has been developed for car audio manufacturers, enabling the replacement of incandescent lamps with LEDs.

FEATURES:
Available as thin as 0.5 mm, yet able to block up to 95% of light and provide effective diffusion
Extremely uniform surface brightness
Light transmissions ranging from 5% to 40%
Available in thicknesses from 0.5mm to 1.0mm, in 0.1mm increments
Available in any color

BACKLIGHT CONSTRUCTION


Because of its high diffusion property, Clarex DR-IIIS can be positioned directly above the LED, with a minimum gap, as shown below.
