Buying Diffusers

Optical diffusers make light beams more diffuse (spatially less coherent) by random scattering. They are used in applications like photography, lighting, and optical measurements to create uniform illumination and reduce glare.

![]() Enhancing Beam Performance PowerPhotonic Ltd.5A St David's Drive Dalgety Bay Fife KY11 9PF United Kingdom | ![]() PowerPhotonic offers unique Gaussian and flat top refractive diffusers for use with multimode beams. The refractive nature of the diffuser means that it imparts a well-defined and tightly controlled divergence angle to an input beam, which can range from fractions of a degree up to 10 degrees (FWHM). This makes PowerPhotonic diffusers ideal for a wide range of applications where precise beam shaping is essential, such as laser tattoo removal, laser skin rejuvenation, laser projection, and source homogenisation. |
