Circular Variable Neutral Density Filters



The Circular Variable Neutral Density filter (UV-VIS-IR) is a filter wheel to linearly attenuate light as the filter is rotated. The CVND filter can be used for white light as well as for lasers. A large finite aperture can be attenuated by counter rotating to filters in series. Sizes are available from 25mm to over 200mm in diameter. Custom sizes and densities are available upon request.
