Shaped diffusers (holographic)
What are you looking for in Stock?
Light shaping, or holographic, diffusers are designed to provide even light distribution in LED, fibre and fluorescent lamp applications and reduce unwanted hot spots by homogenising incident collimated light.
Shaping diffusers are manufactured using a holographic master to produce an anti-reflective surface that diverges light similar to a negative lens. The light divergence is designed to create simple shapes such as circles, ellipses, lines and squares when collimated light is passed through it.
Knight Optical do not offer holographic diffusers as a stock item. Custom holographic diffusers are available on request. For more information on light shaping holographic diffusers and our custom optic service, contact our technical sales team.
