Ultra-Accelerated EMMA (UA-EMMA) provides approximately 10-12 years of equivalent South Florida radiation exposure in a single year. A new mirror system used in the UA-EMMA has very high reflectance in the UV and near-visible wavelength ranges while attenuating reflectance in the longer-wavelength visible and IR portions of the solar spectrum. This allows for very high concentrations of UV energy without excessive heating of test samples. E-mail atlas.info@ametek.com
