1 Laser Safety Windows 51

2 Laser Protection Windows made from mineral glass and plastics Based on available technologies LASERVISION offers laser safety windows and special filters. Independent from the applications, such as large area windows for the laser lab, cabin windows for automated laser work stations or customised filters for special set-ups LASER- VISION offers a safe solution for every application according to the standards. Mineral Cabin Window Laser safety cabin windows from LASERVISION consist of a composite structure of a highly absorbing mineral glass and a thin neutral carrier glass. In case of a laser induced thermal break or any other accident, this lamination prevents the window from falling apart completely which would leave the user exposed to the laser; and secondly it prevents from any injuries caused by glass splinters. The protection even of such a cracked filter remains nearly stable and as high as before. Laser safety windows are used as inspection windows in automated or manual laser material processing systems (welding, cutting, drilling) and allow supervision and handling by the user without the need of a laser safety goggle. LASERVISION also offers windows for integration into large area protection systems such as barrier plates or curtains. Highlights Different filter materials available Certified according EN207 and EN208 respectively Lamination is the standard technology Maximum standard dimension of most windows: 297x210mm Customised dimension as option Window frames for two standard dimensions as option Combination with curtains and barriers All mineral glass laser protection windows are CE and in most cases also GS certified and are subject to continuous quality monitoring by our own quality control as well as by independent testing houses. s and protection levels for CE certified windows only D (continuous wave) Protection Level L 10 L 9 L 8 L 7 Wavelength nm nm nm nm T27 T13 T07 > nm T26 > nm L 6 P2009 T nm T06 > nm T nm T nm T nm T nm T nm L 5 T nm T nm T nm T ; nm T nm P nm, nm L 4 T nm T nm T , nm P nm T nm T nm T nm T nm P nm L 3 T06 > nm T nm P , nm T nm L 2 T nm 52

For all applications requiring protection according to the EN 207, LA- SERVISION offers with L-protection levels certified plastic laser safety windows. In all other cases plastic laser safety windows are specified and marked by their optical density only. Project related and for OEM customers LASERVISION offers all filters also as special or small filter version. For that purpose the complete range of filters and manufacturing technologies from LASERVISION is available. The Composite and coating technology from LASERVISION provides laser safety for nearly all applications and working conditions. The biggest advantage of plastic laser safety windows is the availability of much larger sheets and of course their lower weight compared to glass filters. Highlights: Different filter materials available according EN207 on selected materials OD marking as standard Maximum dimension: 1220mm x 915mm (P2001/P2009) Customised dimensions as option Usable as laser enclosure or large inspection window Mountable in frames or in combination with barrier plates CE certification as option 53
