14CNDF-25-90/01-1 - Variable Neutral Density Filter
OVERVIEW
Variable ND filters by STANDA.
Circular ND filters provide continuously variable, linear attenuation of light by rotating the filter around its center. Transmitted intensity varies as a function of the optical density range. The filter can be used for white light as well as for lasers. A large finite aperture can be attenuated by counter rotating two filters in series. Sizes are available from 25 mm to over 100 mm in diameter.
