Diffusion Filters

A range of solutions for softening and spreading a light beam and reducing the contrast ratio between highlight areas. The range includes polyester diffusion filters, frosts, flexi-frosts, perforated diffusion, grid cloths and spun materials all in different densities for a wide range of lighting effects.

LEE Diffusion Index (LDI)

Use the slider to select the level of Diffusion you require and see the products we recommend below.

The LEE Diffusion Index (LDI) has been created to enable easy comparison of diffusion capabilities across our range.

Diffusions

Spread the projected beam of light over the subject, some loss of light will possibly be seen. The greater the diffusion, the greater and more even the resultant spread of light. Shadows are reduced. Used to smooth out beam scallops when lighting cycloramas or in tight spaces.
