Engineered Diffusers™

Engineered Diffusers™ represent a revolutionary concept in diffuser technology.

Engineered Diffusers ™ are advanced beam shapers capable of homogenizing an input beam while shaping the output intensity profile and the way light is distributed in space.

Product format

Engineered Diffusers ™ can be fabricated in various formats:

1.Polymer-on-glass, POG, (replicated polymer on a glass substrate)

  • Lower tooling costs compared to etching, embossing, or injection-molding
  • High-fidelity replication
  • Highly competitive for parts sizes smaller than about 6x6mm
  • Variety of polymers available for:
    • High damage threshold
    • Improved UV transmission down to 320nm
    • Dicing and core drilling
    • Reflow processes
    • AR-coating
  • Typical lead time for a new design: 6wks
