Blue-Violet Tinted Filter Glass
Description
Blue-violet tinted filter glasses with variously specified UV transmittance and high with absorption in the visible and infrared range, as well as clear filters with graded UV transmittances. All filter glasses feature treated edges and are thermally toughened. UVILEX® 390 Z blocks ultraviolet radiation from artificial light sources. Consequently organic materials can be exposed to radiation for considerably longer periods. Used primarily for shop windows and display areas.
A garment made of fur is exposed to daylight at a luminance of 1,000 lux daylight. In this case the permissible exposure time without incurring any fading is about 300 hours. With a conventional tungsten halogen lamp double this exposure time (600 hours) is possible. By using UVILEX® 390 Z the exposure time is increased by as much as four times, so that the fur can be exposed to light for a total of 1,200 hours.
