Neutral Density Filters

Related Products



LINOS's reflective neutral density filters enable optical attenuation over an extremely broadband wavelength range from 400 nm to 2000 nm. The spectral distribution of the light remains unchanged. The optical density D ranges from 0.3 to 3.0 (transmission of 50% to 0.1%).

The filters are made of 2 mm thick borosilicate glass with metal layers vapor-deposited on one side and are available in the sizes Ø1/2", Ø22.4 mm and Ø50 mm. The Ø1/2" and Ø22.4 mm versions are also available with Ø16 mm and Ø25 mm mounts.

Incident radiant power Φ0

Transmitted radiant power ΦT

Transmittance τ = ΦT / Φ0

Optical density D = log10(1 / τ)

    
  • Specified wavelength range: 400 nm - 2000 nm
  • Metallic films vacuum-evaporated onto borosilicate glass substrates
  • Hard and durable
  • Firmly adhering
  • Mounted and unmounted versions available
  • Mounted types fit to LINOS Microbench or LINOS Nanobench
    • 
  • Thickness of all filters: 2 mm
    
  • Custom items (different materials, dimensions, or optical densities) available for higher quantities upon request.

Typical transmittance curves of LINOS's reflective neutral density filters.

 Neutral Density Filters

Application example: By installing a mounted neutral density filter inside a Mounting Plate 25, Lachable, 10°, the reflected part of the beam is deflected sideways and finally blocked by a laterally mounted Mounting Plate Without Hole. A reflex back to the laser is thereby prevented.
