Metal Coating Neutral Density Filter

Metal Coating Neutral Density Filter

Metal coating neutral density filter  is the type of ND filter to reduce the transmittance by reflecting the incident light.

 Metal coating neutral density filters have constant density values across the surface. The transmission to reflection ratio varies with density selection. In stacks, the total density is the sum of each filters density. ND filters are used primarily for the attenuation of light over a wide spectral range. They are often used in laser and photometer applications, where excessive power can cause damage or inaccurate results. Orient mirrored side toward source at 0^o angle of incidence.
