Xe-arc and fluorescent light fading units are used to measure the resistance against light, moisture and heat.
The Xenonlamp simulates the daylight because they have the same wavelength. This is how the device can measure light-influence that would normally take years, in just a couple of weeks. Moisture can be sprayed on the sample to measure the moisture-resistance. Heat-resistance is measured by altering the temperature. This Owner has extensive R&D capabilities in the optics engineering world.
