Circular Variable ND Filters: ZnSe (600nm to 15.0 microns)

The circular variable neutral density filter wheel is a device to linearly attenuate light as the filter is rotated. 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 200 mm in diameter.
