Benefits of High Irradiance Testing

  • Larger sample turnover
  • Lower testing costs
  • Faster time to market
  • Earlier failure detection
  • Reduced risk of extrapolation
  • Important for long-living durable products

High Irradiance Weathering Testing - The Track to Faster Results

Today, only companies that can quickly introduce superior products to the market are able to survive a globally competitive environment. Accelerated and accurate weathering testing is a critical component in product development for any material expected to withstand the damaging effects of sunlight, heat, and moisture. 

Weathering testing  at higher irradiance levels than the normally applied "1-sun" can produce degradation results in a much shorter period of time. Currently,many basic laboratory weathering standards allow up to 3-sun testing. If the principle of reciprocity holds true for a given application, one can either considerably reduce the test time or limit the risk of extrapolation by accumulating a higher solar radiation stress to specimens.

Atlas offers a variety of xenon and metal halide laboratory instruments, testing chambers, and custom-designed systems for high irradiance testing as well as solar-concentrating systems that provide the necessary tools for conducting outdoor testing and research using high irradiance levels.

Some of our products

Ci5000 Weather-Ometer® HE

The Ci5000 Weather-Ometer® HE combines high capacity with a rotating rack mounting configuration, which optimizes uniformity of air flow, relative humidity, temperature, and irradiance on sample surfaces. This instrument is specifically designed to perform high-irradiance testing in order to reduce testing time and cost.

Xenotest® Alpha+

Xenotest® Alpha+ is a compact stand-alone rotating rack xenon instrument. Irradiance and temperature are controlled on-rack on specimen level. Its special lamp design and low-infrared filter systems enable high irradiance testing up to 3-sun levels, while simultaneously optimizing test temperature range.
