Surface activation
VUV irradiation for surface activation – high energy and high performance
Irradiation for surface activation calls for lamps that are at the forefront of performance and efficiency.
Activation of inorganic surfaces or plastic surfaces is an indispensable industrial process. Before surfaces can be coated, painted or glued they must be activated. For organic surfaces this is done by oxygen functionalization and for inorganic surfaces by complete removal of organic residues. Vacuum ultraviolet radiation (VUV) delivers perfect results thanks to its high-energy photons.
XERADEX excimer lamps
XERADEX lamps are xenon excimer lamps which are setting new standards in surface activation thanks to their patented pulse mode. Pulse mode produces around four times the radiated output compared with conventional vacuum ultraviolet lamps. VUV radiation enables a series of molecular bonds to be broken and makes XERADEX lamps a frequently more cost-effective alternative to chemical processes, for example in the manufacture of semiconductors and OLEDs or in cleaning glass in the production of LCDs. XERADEX lamps are also leading the way in terms of efficiency. Almost 40% of the electrical energy consumed is emitted as useful 172 nm VUV radiation. XERADEX lamps from OSRAM are therefore among the most efficient on the market. Another outstanding product feature is that the high efficiency of XERADEX lamps enables irradiation systems to be designed without the need for additional cooling. Such compact irradiation systems make it easier to integrate VUV technology in existing installations. Safety precautions: XERADEX lamps produce extremely intense UV radiation that is heavily absorbed by oxygen. Ozone is produced as a result. Adequate ventilation must therefore be provided during their operation. The lamps should be operated only in airtight enclosures. XERADEX lamps are operated at high voltage and may only be connected to original DBD control gear designed for this purpose. Never connect them to any other control gear.
