The SunEvent allows these influences to be investigated under controlled and accelerated laboratory conditions.\r\n\r\nSolar simulation is provided by metal halide lamps with a global solar radiation spectrum according to CIE 85, Tab 4. Irradiance can be adjusted between 400 and 1,150 W\/m\u00b2. For testing according to DIN 75220, an irradiance of 1,000 W\/m\u00b2 is factory-set and verified on the defined reference plane.\r\n\r\nThe combination of solar simulation, temperature control, and humidity conditioning enables realistic environmental testing within a single test system.","button":null,"text":{"title":"","description":"","button":null},"gallery":"","references":"","tabs":[{"title":"Product Overview","description":"SunEvent test chambers simulate the effects of sunlight and climatic environmental conditions on the properties and service life of a test specimen.\r\n\r\nThe light from the irradiation unit installed above the test chamber is coupled into the test space through a temperature-controlled, double-glazed filter system.
