Strumenti per misura radiazione UV in dermatologia

Description:

UV is widely used by dermatologists in the treatment of certain skin diseases like Psoriasis and Vitiligo. Whole body exposure booths and hand and foot units employing light sources which emit broadband UV-A, UV-B, narrowband 311 nm UV-B and combinations of- UV-A and UV-B are used to irradiate the patient. To measure these light sources Radiometers with a precise spectral match to the spectral ranges of interest with low crosstalk between UV-A and UV-B are required for accurate dosimetry and quantification. The XD-9501 detector head consist of an UV-A and UV-B sensors whose spectral sensitivity and cosine corrected field of view meet accepted UV-A & UV-B spectral standards. Cosine correction of the detectors is of equal importance in achieving low measurement uncertainties. The X9 6 is simple to operate. To measure, connect the detector and switch on the Meter. Selection of the UV-A, UV-B or UV-B311 easily done in the menu mode. The Optometer offers CW and Dose measurements.

Instrument calibration is traceable to the ISO EN 17025 accredited part of Gigahertz Optik`s Calibration Laboratory for Optical Radiation Quantities.

Calibration of UV-A and UV-B Irradiance sensitivity as well as an additional narrow band UV-B calibration at 311nm for TL-01 type sources is supplied. Individually measured plots of the UV-A and UV-B spectral sensitivities are provided as part of the calibration certificate.
