Class Information
Number: 359/227
Name: Optical: systems and elements > Light control by opaque element or medium movable in or through light path
Description: Subject matter comprising the control of the amount of light transmitted through an area defined by an optical beam via an element or material, which is either completely opaque or opaque only in certain portions whereas the other portions are transparent, by (1) selectively intercepting the light path by the element or (2) changing the orientation of the element within the light path.
