UV Filters   • Glasslite UV-filters are used to block the harmful effect of UV-rays. When the luminaire requires a filter glass, toughened float or Borosilicate glass is not sufficient.     High performance lamps not only produce visible light, but also aggressive ultra-violet radiation. The undesirable impacts of UV-rays are:     − Damage to the eyes and skin. − Bleaching of colours, e.g. in textiles or artworks. − Yellowing and brittleness of plastics. − Attraction of insects.   Advantages of UV Filter Glass: • High transmission in the visible spectrum. • High transmission in the near IR-spectrum. • Low and only slightly fluctuating colouration. • Low solarisation (= loss of light transparency   by UV-light). • Maximum service temperature 700-750°C. • Thermal shock resistance up to 800°C.   Owing to their UV-absorbing characteristics and very good price-performance ratio, Glasslite UV-filters are widely used as standard protection glass for many display lighting applications. The bleaching of the exhibits is considerably decreased, allowing longer periods of lighting.   • Applications: − Lighting of exhibits. − Shop lighting. − Artwork and galleries. − High performance spotlights as the   protective glass has a temperature resistance of up to 700°C.     • Processed in a wide variety of   shapes and sizes to meet specific requirements.     • Glass thickness   Standard 3mm.     Other thicknesses available - 2, 4 and 5mm. Also in grooved spread lens and honeycomb structure pattern.     Note UV - Filters are an import item. Surcharge, minimum quantities and lead times apply.   Photo courtesy of Zumtobel Lighting
