Neutral-density filters



Attenuate polychromatic light without altering its spectral distribution

Transmittance τ = ΦT / Φ0

Optical density D = log 1 / τ

    
  • Metallic films vacuum-evaporated onto glass substrates
  • Hard
  • Durable
  • Firmly adhering
  • Mounted and unmounted versions available
  • Mounted types fit to LINOS Microbench m or Nanobench n
    • 
  • Thickness of all filters: 2 mm
    
  • Custom items (different materials, dimensions, or optical densities) available for higher quantities upon request.
