Home > Filters > 14CNDF - Circular Variable Neutral Density Filters
Circular Variable Neutral Density filter is an economical solution to attenuate the light
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
