Highly durable, chemically resiliant and scratch resistant plastic diffusers from Knight Optical.
Optolite™ HSR plastic diffusers offer superior, more uniform diffusion than ground glass and have a number of uses including backlighting, colour comparison, fibre optics, liquid analysis equipment and a range of entertainment and design applications from the laboratory to the high street.
Knight Optical supplies quality Optolite™ HSR plastic diffusers manufactured in the United Kingdom. Our diffusers offer excellent chemical resistance and durability for outstanding performance and long operating lifetimes whether placed indoors or out. Optolite™ HSR plastic diffusers have up to 20 times the abrasion and scratch resistance of equivilent acrylics and are highly impact resistant. Our diffusers are approximately half the weight of equivilent glass and can operate continually in temperatures in excess of 100°C.
Our stock range of 3.0mm thick, Grade 2 diffusers give excellent diffusion and moderate transmission designed for common soft lighting and diffusion applications. We offer a comprehensive bespoke service for custom diffuser specifications for alternative sizes, thicknesses and grades. Thinner material should be used where better Lambertian diffusion is required or space in the system or design is limited. Thicker diffusers offer higher impact resistance for exposed environments such as shop displays.
