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. Float Glass 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
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.
