Edmund Optics Inc.
Edmund Optics has released fully tunable electronically variable optical diffusers. They use a liquid crystal film to vary the degree of optical diffusivity from near-Lambertian to clear.

The diffusers feature a spectral range of 400 to 1500 nm, a 25-mm aperture, transmission of 85% and a response time of 10 to 20 ms. With C-mount mounting threads, they are compatible with the company’s full range of C-mount...See full product
