Rayotek’s high-performance diffusers and Optical Homogenizers have been developed for ultraviolet (UV), visible (VIS) and infrared (IR) laser and light applications. Due to proprietary manufacturing processes, Rayotek’s diffusers have 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 high performance diffusers consistently reliable. In addition, long diffuser lifespans directly reduce system down times caused by signal degradation (a possible source of signal error issues).

BENEFITS TO YOU:
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

 

DIFFUSER SPECIFICATIONS:

Full Width Half Maximum Range: 5° to 40° with tolerances better than +/- 0.5
