PMA2110 UVA
Detector |
|
 |
FEATURES
 | High sensitivity |
| Dynamic range 2*105 |
| Excellent long term stability |
| Cosine corrected |
| NIST traceable calibration |
| Radiometric units |
|
| The PMA2110 UVA detector provides fast and
accurate irradiance measurement in the UVA region. Its spectral response covers the 320 to
400nm range. The Teflon diffuser assures an angular response close to a cosine
function (Lambertian response) making it suitable for measuring diffused radiation or
radiation from extended sources. |
APPLICATIONS
| Laboratory and industrial radiometry |
| UV curing, printing and photolithography |
| Skin and SPF testing |
| Clinical studies |
| Phototherapy |
| Environmental monitoring |
| Material testing |
| UV-A transmission measurements |
|
| The PMA2110 detector 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
