OPTICAL LIGHT DIFFUSER & OPTICAL LASER DIFFUSER

Rayotek's High-Performance Optical Light Diffuser (also known as Optical Laser Diffuser and Optical Homogenizer) has been developed for ultraviolet (UV), visible (VIS) and infrared (IR) laser and light applications. Due to proprietary manufacturing processes, Rayotek's Optical Light Diffuser has higher transmission and power damage threshold limits compared to traditional fused silica, opal and ceramic diffusers.

Low to zero speckle and highly uniform surfaces make Rayotek's Optical Light Diffuser consistently reliable. In addition, long light diffuser lifespan directly reduces system down times caused by signal degradation (a possible source of signal error issues).

BENEFITS OF OPTICAL LIGHT DIFFUSER & LASER DIFFUSER:

Very low speckle
Thermal stability (zero drift over time)
High transmission over a broad spectral range
Reduction in system down times
Cone angles customized to requested needs
Thermal shock resistance
Excellent signal homogenizing
