XD-9501-4
UV-A, UV-B, UV-B_311nm Irradiance Detector
UVA, UVB and Narrowband UVB Phototherapy Dosimetry and Photobiological Studies

The XD-9501-4 two-cell detector includes two filtered corrected photodiodes. One for UV-A 315-400nm and the other for UV-B 280 to 315nm spectral responses. Both detectors are calibrated with a spectrally broadband calibration lamp for UV-A and UV-B irradiance in mW/cm². An additional calibration of the UV-B detector is done using a 311nm calibration standard light source for irradiance sensitivity at 311nm for narrowband UV-B type sources. The detector is supplied with a 2m long coaxial cable with -4 type connector for use with Gigahertz-Optik’s X11, X12 and X1-PCBC optometers. Calibration of UV-A, UV-B and UV-B311nm irradiance in W/m² and W/cm² is performed at Gigahertz-Optik’s Calibration Laboratory for Optical Radiation Quantities.
