    Abstract: An optical beam dump (30), (51) having a passage defined by a passage wall and an optical filter (33), (55) located in an opening in that passage wall. The optical filter (33), (55) being arranged to direct light reflected from that filter (33), (55) along the passage away from an optical input (32), (65) to the beam dump. The passage may be formed as a tube (31), or may be cut within a block of material (52). The passage may have a plurality of bends. Provision for the flow of purging air through the beam dump is made by providing holes (36), (61) in the passage wall.
