Different Configurations of Circular Diffuser Film

DFPM Grade Diffusers are translucent, 1/side matte, 1/side luster film that can be used under a variety of lighting conditions. The luster surface provides a bit of specular back reflection. This grade is made from a rugged PET base film, and is available in a variety of thicknesses and sizes.

DFPMHT Grade Diffusers are a slightly higher-transmission version of DFPM Grade Diffuser Film, a is a 1/side matte, 1/side gloss film that can be used under a variety of lighting conditions. The gloss surface provides a specular back reflection. This grade is made from a rugged PET base film, and is available mostly in .003″ and .004″. Other thicknesses are custom.

DFMM Grade Diffusers are translucent, 2/side matte film that can be used under a variety of lighting conditions except polarized light. Two layers of matted finish provide maximum diffusion. Made from a rugged PET base film, DFMM is available in a variety of thicknesses and sizes.

DFIM Grade Diffusers are translucent, internal matte film that can be used under a variety of lighting conditions except polarized light. 2/side luster, internal matted finish provides maximum diffusion at an economical price point. This grade is made from a rugged PET base film, and is available in a variety of thicknesses and sizes.

LBMT Grade Light Diffuser Film is a 1/side matte, 1/side gloss clear film. Its low, uniform birefringent properties make it ideal for diffusing polarized light. This is a lighter diffusion product with maximum transmission – more aggressive than anti-glare film, but not as hazy as our other products. And it can also be thermoformed!

LBOM Grade Light Diffuser Film is a 1/side matte, 1/side gloss clear film. This ultra-bright white film can be printed with solvent and UV inkjet, as well as conventional printing methods, for use in back-lit signage. Its bright white opalescent quality really makes colors pop!  It is also a very aggressive diffuser. And it can be thermoformed!
