M-Series Diffusers

M-Series diffusers are used in spot and narrow flood lighting to smooth beam artifacts caused by parabolic, Fresnel, or TIR lens collimators without significant broadening. The unique mixing design provides superior far-field smoothing and color mixing with high on-axis brightness. Compared with traditional diffusers, M-series diffusers maintain higher central beam candlepower (CBCP), and produce less undesirable “field light” at higher angles.

Usage Notes

  • M-Series diffusers may be used in either orientation. BrightView recommends using the microstructures facing toward the LEDs or lamps
  • Choose the minimum-strength M-Series diffuser that provides the needed smoothing
  • M-Series diffusers do not have focusing power – they are designed for use in conjunction with parabolic, Fresnel, TIR, or other collimation optics
  • BrightView applications engineers can assist with product choices and help your design achieve peak performance 

Angles and transmissions are typical; they vary greatly depending on luminaire design.
