| UVA Detector with Beam Splitter Adaptor
The measured irradiance is displayed in mW/cm2 or W/m2. Consequently, the integrated dose is shown in Joules/cm2 or kJoules/m2. The PMA2114 has a resolution of 0.001 mW/cm2 and a full scale of 200mW/cm2 allowing measurement of very week and very strong signals with the same detector. The effect of stray light is negligible. In conjunction with the Solar Simulator and XPS200 Xenon Lamp Power Supply the PMA2100 with the PMA2103 detector can operate as a smart dose controller/monitor substantially enhancing the functionality of the Solar Simulator. 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. Several biologic action spectra, functions relating wavelength of the radiation and its biologic effect, are shown in Figure 3. While they all sow strong dominance of UV-B effectiveness there is still fair UVA response. Common sources of UV-A include:

APPLICATIONS
|
The PMA2114 UVA detector provides fast and
accurate irradiance measurement in the UVA region from Solar Simulators manufactured by
Solar Light Co. Special mounting hardware allows direct coupling with the beam-splitter
available for 15S and 16S Solar Simulators. Its spectral response covers the 320 to 400nm
range (Fig. 1).
