XD-9506

Detector Head for use in UV Photo-biological Hazard Measurements

UV-A and UV-BC actinic UV irradiance
IEC/EN 62471 and DIN EN 14255
ICNIRP / ACGIH (>240nm)
For use with X1 Optometer

Several guidelines and standards for UV hazard risk assessment exist today. The ICNIRP spectral weighting function for Actinic UV, S(λ), is most commonly required. For example, it is specified in IEC and EN 62471, DIN EN 14255, ANSI RP27.1, and 2006/25/EC. The XD-9506 incorporates a two sensor design that offers best possible isolation between the UV-A_effand UV-B_eff sensors while providing the closest spectral match to the ICNIRP S(λ) actinic UV weighting function.

ACGIH / Far-UVC measurements

Prior to the publication of their Threshold Limit Values (TLVs) in 2021, the American Conference of Governmental Industrial Hygienists (ACGIH) specified the same actinic UV weighting function, S(λ), as IEC 62471, etc. The current edition of ACGIH TLVs reduces this weighting function in the wavelength range below 240nm. The XD-9506 is not suitable for hazard measurements of far-UVC sources such as Kr-Cl excimer lamps that exhibit strongest emission at 222nm. The photobiological safety of such lamps is very dependent on the filtering used to block longer wavelength UVC radiation. Such measurements should be performed with the Gigahertz-Optik BTS2048-UV spectroradiometer. The XD-9506 is suitable for all ACGIH UV hazard measurements of sources with no emission below 240nm

Traceable calibration

Calibration of the detector ICNIRP (W/m²) responsivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik calibration of absolute detector responsivity as well as detector individual measured relative spectral responsivity data is included.
