Neutral density filter

Neutral density filters are reflective ND filters that are used to diffuse light intensity. The coated chrome film reduces the light by mainly reflecting and partially absorbing it.

Asahi’s ND filters are designed to provide uniform spectral performance, particularly in the VIS range, without changing the relative spectral distribution of energy. Nevertheless, they are available from the UV to the IR range, as the carrier material is quartz glass. Six different attenuation levels are available.
