Commercial Grade Reflective Neutral Density Filters

These filters have constant density values across the surface. In stacks, the total density is the sum of each filter’s density. ND filters are primarily used 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 an angle of incidence of 0°.
