CLAREX High Transmission Light Diffusers (DR-IIICX)
High transmission bulk diffusers for backlight applications and more
The factory loads light scattering particles into the clear cast acrylic sheets along with heavy matte textures front & back to make this line of diffusers. With light transmissions ranging from 45% to 93% in 5% increments, you can choose the transmission level that gets you the maximum brightness and uniformity without hot spots.
These diffusers are commonly used in place of OEM LED backlight diffusers. Customers get an immediate boost in brightness without reducing the uniformity.
The standard DR-IIICX diffusers are pure white with minimal color shift, making them great for flash/light diffusion where color rendition is critical.
