Features & Applications:
The Radiometer UVA Sensor provides fast and accurate irradiance measurement in the UVA region. Its spectral response covers the 320 to 400nm range. The
protective coated diffuser assures an angular response close to a cosine function (Lambertian
response) making it suitable for measuring diffused radiation or radiation from
extended sources.
The UVA Sensor is ideal for measuring
mercury, xenon, metal halide or fluorescent lamps, commonly used for studies in
the UVA region, as well as sunlight.
The measured irradiance is displayed in mW/cm2 or W/m2.
Consequently, the integrated dose is shown in Joules/cm2 or kJoules/m2. The
PMA2110 has a resolution of 0.001 mW/cm2 and a full scale of 200mW/cm2 allowing
measurement of very weak and very strong signals with the same detector. The
effect of stray light is negligible.
UVA is less biologically effective than UV-B (280-320nm).
However, because of its much greater intensity in sunlight and many artificial
sources and the greater period of the day in which sunlight UVA remains at high
intensities, UVA can have significant biological effect. The UV-A radiation can
also penetrate deeply into human living tissue through the skin. Commonly known
effects of UV-A include: photosensitization of various chemicals, pigmentation
of the skin, induction of polymerization. The UVA can also cause erythema or DNA
damage in humans or animals, however large doses of UV-A are needed and the
damage mechanisms are different than these of UV-B.
