Nov 12, 2012 Utilizing liquid crystal film to vary degree of optical diffusivity from near-Lambertian to clear, Electronically Variable Optical Diffusers feature spectral range of 400–1,500 nm, 25 mm aperture, 85% transmission, 10–20 msec response time, and C-Mount mounting threads. Diffusion angles (FWHM) range from 1° in the clear state to 70° in the fully diffused state and can be continuously adjusted using control knob. Uses include research and prototyping as well as Life Sciences applications.

Sep 08, 2011 Available with 5 or 10 mm clear aperture and diffusion angles of 1, 10, and 20°, Laser Speckle Reducers remove local interferences and minimize speckle noise in laser systems. Units utilize 4 electro-optic polymers, which selectively move each reducer's central diffuser along X and Y axis to form circular pattern of motion. Powered by USB, reducers are suitable for beam homogenization, 3D scanning, metrology, microscopy, and interferometry applications.

Jun 13, 2007 Light Diffuser Masterbatches are manufactured by using polymer-based diffusion compound formulated for polycarbonate, acrylic, and other clear plastics. Used to eliminate hot spots caused by LEDs in applications such as signage and illuminated knobs, products contain spherical polymer particles that scatter and spread light in plastic sheets and films to form even illumination, while allowing light transmission levels of 90% or more.
