Neutral Density Filters act like “sunglasses” for your system and can be used with black & white or color cameras. They are intended to reduce light intensity neutrally over a specific wavelength range without impacting image color or contrast
ND SERIES NEUTRAL DENSITY FILTERS – VISIBLE (VIS) SPECTRUM
ND filters include identical male and female threads on either end so that they can be stacked with other ND filters to achieve various optical densities.
Applications include imaging in intense lighting situations, aerial imaging and photography.
Key Benefits in Industrial Imaging:
Absorptive filter effective from 425-675nm
Available in optical densities ranging from 0.10-6.0
Ni SERIES NEUTRAL DENSITY FILTERS – VISIBLE (VIS) SPECTRUM
Ni filters are used to limit visible and/or near-IR light, reducing the quantity reaching the camera sensor, thus allowing for longer exposure times and reduced depth of field.
These filters include identical male and female threads on either end.
Key Benefits in Industrial Imaging:
These filters help reduce shutter speed to create blur, preventing a “jello” effect in aerial imaging.
Low reflectivity filters that iare effective from 400-2000nm
Available in optical densities ranging from 0.3-2.0
Coated on low-expansion, heat-resistant Borofloat® glass
