Abstract
A flexible laser safety curtain is disclosed that utilizes a plurality of columns flexibly attached to one another along their longitudinal edges in such a manner as to create a curtain of columns. The base of each column contains a cavity within which at least one moveable element, columnar in form, may be located and protrude from the cavity. The moveable element, when pressed against a work surface, is forced into the cavity. A biasing element within the cavity provides an opposite force on the moveable elements to both keep the moveable element in contact with the work surface, and to return the moveable element to its original position when the inward force is removed. The curtain's edge follows the contours of an uneven work surface and thereby the curtain provides a complete barrier to laser radiation.
