Absorptive Optical Glass Neutral Density Filters are available with Optical Densities(O.D.) ranging from 0.10 to 4.00. Absorptive Neutral Density Filters Attenuate incidence Visible light by absorption within the glass substrate; allowing for a nominal amount of transmitted light from 400-700nm. These Filters are used in applications such as calibration filters, where minimal reflection of incident light is required.
For more information about Absorptive Glass ND Filters , refer to our Optics Tutorial page.
