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.
BENEFITS
- Provides attenuation with greater linearity over a wide spectral range
- Reduces thermal effects in low-power laser applications
- Delivers superior durability
COMMON APPLICATIONS
- Calibration
- Attenuation
- Low-power lasers
- Scientific measurements and research
- Machine vision & other imaging
Optical density (OD) is defined as the logarithm to the base 10 of the reciprocal of the transmitted radiant power (T):

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.
