The SWARO LENS A02 with asymmetrical light distribution is suited for a wide range of optical illumination, it was optimized for the use in tunnel areas. Swarovski special glasses, which are used in the production of our lenses, are highly transparent in the visible (VIS) and near infrared (NIR) wavelength ranges. The internal transmission of the glass at a layer thickness of 10 mm exceeds 99 %. Due to the high transformation temperatures (TG) our lenses can be used up to a maximum temperature of 450 °C. Swarovski special glasses also feature highest levels of resistance against acids, bases, phosphates and climatic influences.
