Solar simulation chambers from Weiss Technik GmbH and Atlas MTT. Direct sunlight, heat, cold, and humidity. Almost all everyday objects are subject to these environmental influences, which have a direct impact on their service life. Fading colors and accelerated aging of materials. For many products, testing for light resistance in combination with other environmental influences is therefore essential. Both of our partners are pioneers in the development of technologies for accelerated testing of materials' resistance to solar radiation (known as solar simulation). Their devices can be found in the laboratories of renowned automotive parts manufacturers, development laboratories in the chemical, pharmaceutical, and cosmetics industries, and many other sectors. They are also used in certification testing laboratories around the world. In addition to our own devices, we also offer natural exposure services for samples at several centers around the world.
