Abstract

1446734 Welder's eyeshield GOTAVERKEN AB 28 Aug 1973 [4 Sept 1972 13 March 1973] 40459/73 Heading G2J A welder's protecting eye-shield e.g. in the form of goggles or in one piece comprises a multi-layer interference filter which transmits in a narrow band covering the wavelength of yellow sodium light and, preferably, in at least one further narrow band in the range 570-600 mm. The transmission bands lie in dips in the intensity distribution of light emitted by the welding process and at the same wavelength as the emission lines of the discharge lamps used to illuminate the workpiece. Thus the shield protects while welding and yet allows the welder to see about himself clearly without removing the shield while not welding. The eye-shield may take the form of partspherical filters mounted in a frame so that, when worn, the centre of curvature of each filter lies at the centre of the corresponding eye. Alternatively a single element may be used either of simple curvature or shaped to have a convexity in a horizontal and a vertical plane. The filter does not transmit I.R. or U.V.
