Diffusers and screens
Description
Anti-Newton glass gives the weakest diffusion effect. This lightly-etched glass is used to support film in enlargers etc. without interference fringes (Newton's rings) appearing.
Ground glass gives a diffusion angle of about ±10o and is useful for focusing screens and for weak diffusion in illuminating systems. We list both LEBG and UV silica (See optical materials).
Acrylic and PVC: our plastic screen materials have a controlled diffusion, allowing an image to be back-projected on a large screen without 'hot spot', and have a grey tint to minimise reflection of ambient and scattered light. The 0.3mm PVC material, with a gain of 2.3, is normally stretched over a rigid frame, whereas the 3mm acrylic (with gain of 4.7) is self supporting.
Flashed opal glass has nearly Lambertian characteristics (luminance independent of viewing angle) and is used in light boxes and illumination systems where strong diffusion in needed.
