WebAbsorption by ozone takes place in the upper atmosphere at heights above 40 km. It occurs mainly in the ultra-violet region of the spectrum, where it is so intense that very little solar radiation of wavelength less than 0.3µm reaches the Earth's surface. About 3% of the solar radiation is absorbed in this way. WebThe IEC 60904-9 introduces the A+ classification in all three metrics of spectral match, spatial non-uniformity and temporal instability. The new standard also extends the required wavelength range for solar simulators to claim Class A+. Before, 400 nm to 1100 nm was sufficient for reproducing 1 sun. Now, a solar simulator needs to be evaluated ...
