ISO 9001 - AS 9100 - ITAR Standard & Custom Optical Filters and Coatings

IMAGE QUALITY METALLIC NEUTRAL DENSITY FILTERS UV-VIS-NIR

Neutral density (ND) filters are useful in a number of applications such as attenuators for broadband spectral sources, partial reflectors for light balancing applications and for use as neutral beamsplitters. Metallic type neutral density filters obtain their optical density by depositing a metal alloy coating onto a specific type of substrate which is determined by the wavelength region of interest. TWF 1/4 wave. Parallelism < 5 arcsec. UV Grade Fused Silica substrates available in custom sizes

 

*HIGH VOLUME* - This product lends itself to being produced in large quantities at competitive pricing. Email info@andcorp.com or fill out a contact form for details.

 

 

 

Metallic filter Benefits

  • Provides attenuation with greater linearity over a wide spectral range
  • Reduces thermal effects in low-power laser applications
  • Delivers superior durability
Metallic filter Common Applications
  • Calibration
  • Attenuation
  • Low-power lasers
  • Scientific measurements and research
  • Machine vision & other imaging    

 

Please note that all of our ND filters are also available in sets, which include a hardwood storage box.

Custom sizes, densities, wavelengths and substrate materials are available on request.

Contact us for a quotation, whether it is for prototype quantities, or production quantities.

 

Optical density (OD) is defined as the logarithm to the base 10 of the reciprocal of the transmitted radiant power (T):

λθ = λ0  [1 (Ne)2 Sin2θ ] 1
