Neutral density filters

Our supplier is a leader in flat response neutral density filters in the UV to near infrared (250nm-2000nm) and far infrared (2000-14000nm). These coatings are hard and pinhole-free, with any optical density possible at any size. The coatings exhibit industry-leading spectral neutrality over a broad wavelength range, with optical densities up to 4.0.

Metallic neutral density filters

Metallic-coated neutral density (ND) filters obtain their optical density from a metal alloy coating on a substrate determined by the wavelength region of interest. Unlike the all-dielectric or ...

Absorptive neutral density filters

With their ability to minimize back-reflections and scattered light, absorptive neutral density (ND) filters are ideal for calibration. In contrast to the metallic type, absorption-type filters ...

Neutral density filter sets

Absorption and metallic-coated neutral density (ND) filters. The metallic coated type ND filters employs a combination of absorption and reflection to reduce the intensity of lights. The absorptive ...
