A Solar Radiation Test Chamber is a specialized environmental test chamber designed by Envisys to simulate the effects of solar radiation, temperature, and humidity on materials, components, or products. These test chambers replicate the natural sunlight or sun-rays conditions to test how long-term exposure of objects to sunlight or sun-rays and other climatic conditions impact the durability, performance, and lifespan of these objects viz., automotive parts, electronic goods, defence or aerospace systems etc., The simulation of solar radiation involves the reproduction of full spectrum of solar radiation consisting of ultraviolet (UV) rays, visible light, and infrared (IR) radiations. Metal hallide lamps are often used to simulate the required solar spectrum in the test space to study the DUT’s degradation due to UV, visible and infrared radiation. They key charecteristics of metal hallide lamps are their broad spectrum, high intensity and high efficiency.
