Optical radiation from artificial and natural light sources can effect a photobiological reaction on human skin and eye with the risk of damage due to overexposure. Regulations, standards and guidelines that include effective limit values are published for equipment safety and occupational safety in the workplace. Equipment safety requirements that are internationally agreed on require manufacturer’s to classify, design criteria and warning labels for their products, whereas workplace safety tends to be more national requiring health hazard protection of employees including published exposure limit values, threat analysis and precautionary measures. The most current regulations are:
- EN 62471 for Equipment Safety
- 2006/25/EC Guideline and DIN EN 14255 for Safety of Workplaces
Gigahertz-Optik GmbH, as a world class manufacturer of high-end filter photometers, colorimeters and radiometers has manufactured light meters for light hazard measurement and assessment since 1992. The early single sensor design of the hazard light meter was later replaced by dual or multi-cell detectors for improved measurement uncertainty and also for simpler operation. The latest design model X13 (X_one_three) light hazard meter conforms to the 2006/25/EG, DIN EN 62471 and EN 14255-1 measurement criteria for the evaluation of hazard exposure. It is a supplemental or alternative measurement method to the double grating monochromator spectroradiometer the most accurate UV radiometric instrument for this application. The double monochromator based instrument is expensive, laboratory based, delicate and includes multiple parts making it difficult to move. Now a portable, hand-held and lower cost solution is available with Gigahertz-Optik’s X13 light hazard meter. The complete X13 instrument consists of the compact X13 meter, XD-45-HB Blue Light Hazard Detector and XD-45-HUV UV Hazard Detector. It is designed specifically for the evaluation of the potential health risk due to exposure from UV and Blue Light for workplace safety and product classification. Its simple use and price level supports the needs of lamp distributors, light source systems and luminaire manufacturers, institutional and industrial safety engineers, hygienists and others required to perform routine and periodical health hazard optical radiation measurements independently without third party testing laboratories. The light hazard meter is calibrated by Gigahertz-Optik’s calibration laboratory for optical radiation measurement units.
Gigahertz-Optik GmbH emphasizes that accurate conformal UV and Blue Light hazard light measurements require a knowledge of basic radiometry, following proper radiometric techniques and understanding the applicable standards!

X13Meter
For on site light hazard measurements in the ultraviolet, blue and visible spectral range Gigahertz-Optik manufactures different detector heads each in multiple sensor design. The hand-held Gigahertz-Optik X13 meter is the read-out device for these multi-cell detectors for steady state CW light sources. The key features of the X13 meter are:
- Four channel electronics for multi-cell detectors
- Wide dynamic range (0.1pA to 200µA amplifier)
- Low noise for high sensitivity (0.1pA resolution)
- Auto ranging gain control
- Range dependent gain calibration for high linearity over the full measurement range (DAkks traceable)
- Four column alphanumeric backlit display
- Powerful microprocessor operation
- Large data storage memory
- Simple to use menu supported operation
- Ergonomic hand-held meter design
- Battery or USB power operation
- USB interface
Quick Operation Guide:
After switching on the meter the main menu is opened by pressing the menu button. Depending on the measurement application the UV Hazard or Blue Light Hazard detector, connected to the meter, is selected by its model number. The detector calibration data is activated by the enter key and the display is automatically set to the correlating measurement values. If the light source characteristics in the application are not known an average calibration factor is used. A light source emission spectrum dependent measurement uncertainty is factored into the average instruments uncertainty. If the light source can be indisputably identified a light source dependent calibration correction factor can be selected from a library in the menu to reduce measurement uncertainty. The instrument is then ready for actual measurements.
Gigahertz-Optik X11 meter, the base unit of the X13, is one of the most compact and ergonomically styled multi-channel light meters available. It’s simple operation and reasonable price make it the basic meter in many Gigahertz-Optik and other OEM light measurement applications.

XD-45-HUV: UV Hazard Light Detector
The XD-45-HUV irradiance detector is specially designed for the evaluation of light exposure hazard values for artificial light sources. The three sensor design of this unique device covers the requirements for skin and eye risk assessment.
The ICNIRP spectral sensitivity required for skin and eye risk evaluation is formed using two filtered sensors. This prevents the typical cross-talk and limited sensitivity between the UV-A, UV-B and UV-C spectral ranges as with a single filtered sensor solution. Also, a UV-A sensor for the evaluation of UV-A315-400nm human eye risk is integrated. All three detector heads are mounted behind the 20mm diameter cosine diffuser. For measurements of eye dependent irradiance values a front adapter is supplied to limit the detector field-of-view to 80 degrees.
Calibration of the detector ICNIRP (W/m²) and UV-A (W/m²) sensitivity is performed by the Gigahertz-Optik GmbH calibration laboratory for optical radiation measurements quantities. As with all light detectors supplied by Gigahertz-Optik the calibration of the detector sensitivity includes the relative spectral sensitivity data. Having this data available allows the measurement uncertainty of each individual sensor to be calculated for light sources different than the reference lamp used for calibration. This includes a wide range of UV rich lamps as well as simulated UV LED sources. In measurements where the type of light source is known, source specific calibration correction factors are supplied to improve the measurement uncertainty.

SUV(λ) effective irradiance measurement range:
0.5mW/m² to 10W/m² (max. resolution 0.05mW/m²)

XD-45-HB: Blue-Light Hazard Light Detector
The XD-45-HB 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.
The Blue Light Hazard spectral sensitivity required for eye risk evaluation is formed by three filtered sensors for the BLUEUA300-400, BLUE400-600 and BLUERED600-700 spectral ranges. The EN 62471 conformal B(λ) detector is useful for evaluation of any type light source that contains UV-A and deep red light components. Also, a V(λ) photometric sensor for the evaluation of illuminance in lx is integrated to establish the 500lx reference distance protocol for the illuminance and/or radiance qualification. All four filtered sensors are mounted behind the 20mm diameter cosine diffuser.
Calibration of the B(λ) (W/m²) and Ev (lx) detector sensitivity 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 the detectors sensitivity includes the relative spectral sensitivity data. Having this data available allows the measurement uncertainty of each individual sensor to be calculated for light sources different than that of the reference lamp used for calibration. This includes a wide range of lamps as well as simulated LED sources. In measurements where the type of light source is known, source specific calibration correction factors are supplied to improve the measurement uncertainty.
