Neutral Density Absorption Type Filters AT 450-650 nm

EKSMA OPTICS neutral density (ND) filters attenuate VIS spectral region. The optical density varies from 0.1 to 3.0, 1 or 2 inches size square and roud shapes are available.
Neutral density absorption type filters decrease the intensity of light without altering the relative spectral distribution of the energy. They are used to filter the entire visible spectrum evenly, allowing light reduction, without influencing color or contrast. Attenuation is accomplished by using a light-absorbing glass.
