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.
