Product Family Description

Neutral density filters have constant density values across the surface. In stacks, the total density is the sum of each filter’s density. Neutral density 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. Commercial Grade Reflective Neutral Density Filters offer commercial quality, at an affordable price. 

Note: Orient the mirrored side toward the source at an angle of incidence of 0°.
