Eye safety laser measurements according to IEC/EN 60825-1 and 2006/25/EC
LiDAR has gained in importance
Due to the widespread use of LiDAR sensors, from hoover robots to highly complex LiDAR sensors in the automotive sector driven by autonomous driving, the requirements and variety of measurement systems for evaluating laser safety in terms of eye safety are also increasing. We offer innovative measurement solutions especially for pulse measurement with simultaneous power measurement and eye safety.
Requirements for optical measurement according to IEC/EN 60825-1 and 2006/25/EC
According to the mentioned standards IEC/EN 60825-1 and 2006/25/EC, detectors with a 7 mm measuring aperture are required for the measurement of eye safety in laser protection. This diameter corresponds to the average light entrance area of the human eye. Of course, the measuring system as well as the calibration must match the laser to be measured in terms of wavelengths and intensity. Here, our modular system enables us to design a perfectly fitting measurement solution for your requirements.
IEC/EN 60825-1 defines the requirements for the safety of laser products, including the classification of lasers according to their danger (laser classes).
Types of detectors for laser safety measurements
To measure laser power, the detector area must be larger than the laser spot size on the detector surface so that the total radiated power can be measured.
Flat detector head
We offer flat laser detectors with active areas up to 1 cm². Important for laser safety measurement is the measuring aperture of 7 mm in diameter, which is given e.g. by the LP-9901 laser safety detector head. Its flat design and compact dimensions make it particularly suitable for measurements in places that are difficult to access.
Integrating sphere detector
However, integrating spheres, which allow much larger input port areas and laser powers, are also ideally suited for these measurements. Especially when it comes to adjusting the dynamic range and calibration strategy. Adapters or direct 7 mm measurement ports are then possible, see e.g. ISD-1.6-SP-Vxx fast integrating sphere or the larger ISD-5P-SP. By using port reducers, such integrating sphere detectors can be used flexibly.
