Non-Reflecting Neutral Absorbers

Non-reflecting neutral absorbers exhibit spectrally flat transmission with virtually zero reflectance. Transmission levels can be constrained to a specified level without causing reflection. The figure below shows an example where a transmission near 80% was required.

Omega fabricates these parts by grinding and polishing doped glass to a specified thickness, and then anti-reflecting the final part.

  • Custom sizes are available
  • Thickness as specified

Applications for Non-Reflecting Neutral Absorbers
