The XD-45-HB-4 irradiance detector is specially designed for the evaluation of Blue light exposure hazard values for artificial light sources. The four sensor design of this unique device covers the requirements for eye risk assessment. It supports a number of standards and regulations:

IEC 62471:2006 and EN 62471:2008
2006/25/EC
IEC TR 62778:2014

Three Sensor B(λ) Design

The Blue Light Hazard spectral responsivity for eye risk evaluation is formed by three filtered sensors for the BLUE_UA300-400, BLUE_400-600 and BLUERED_600-700 spectral ranges. The IEC/EN 62471 conformal B(λ) detector is useful for evaluation of any type light source that contains UV-A and deep red light content.

Additional Illuminance Sensor

An extra V(λ) photometric sensor for illuminance measurement in lx is installed to establish the 500 lx reference distance protocol for illuminance and/or radiance qualification. All four filtered sensors are mounted behind a 20 mm diameter cosine diffuser.

Traceable Calibration

Calibration of the B(λ) (W/m²) and E_{v (lx)} detector 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.

Steradian Tube for Radiance

The optional XD-45-HB-SRT200 steradian tube is a unique tool for product qualification measurements of blue light hazard at the recommended distance of 200 mm. The tube attaches to the front of the XD-45-HB detector head and includes two exchangeable aperture plates to form a 100 mrad (20 mm diameter) and 11 mrad (2.2 mm diameter) field of view as stated in IEC 62471:2006 and EN 62471:2008 limit values. The tube is made out of light weight plastic with internal baffles and low reflection coating to reduce side wall stray light traversing down the barrel. The XD-45-HB-SRT200 steradian tube is an optionally available detector accessory component. No extra calibration is required.

Recommended Optometers

For applications involving steady state light the X1-3 optometer is recommended. For unstable or short event light the optometer P-9801 should be selected.
