Patent

CA 2306290

A variable optical filter for video cameras designed to variably attenuate certain wave length signals by means of alternating radially oriented areas of coatings which ace opaque or partially opaque to the aforesaid wave lengths. A pair of similarly designed filters can be relatively rotated to cause opaque areas to overlap non-opaque areas and thereby reduce the signal intensity.
