The benefit of an ND filter is a constant attenuation across a range of specified wavelengths. Neutral Density filters are available for any transmission value from 400nm – 2000nm. These filters are available for deposition onto a variety of substrates including glass and plastics. Contact our design team to discuss your ND filter specifications.

Neutral Density (ND) filters are typically expressed in terms of their OD (optical density) – the measure of transmittance through a medium. The OD is defined as -log10(T), where T = transmission.
