Special Laser Safety Considerations for Long-Range Beam Display Heads
Infinity beam lasers with beam display heads are long-range class 4 laser products with extreme output powers. Due to the extraordinarily low divergence, safety distances of many kilometers may apply. The product features a selective, wavelength-dependent and unified irradiance adjustment, not only to increase the reach and brightness of the beam, but also to adapt the maximum permissible exposure (MPE) levels to different setup conditions (e.g. airports in reach). On long distances, also beam movement can significantly reduce safety hazards.

Only especially educated persons should operate such systems. Buyers reveiceive a free laser safety training including the certification according to BGVB 2 (VGB93). Special safety measures have to be taken by qualified staff to avoid risk of eye damage, skin damage or fire. The beam must not be directed into the audience or into populated areas. To avoid such problems, LOBO developed in addition to the integrated safety features also an adjustable mechanical beam block, switching off the moving base and the lasers in case of mechanical contact.

It is highly recommended not to use long-range laser display beam heads indoors. When beams enter aispace, in most countries special permissions by aviation safety authorities are required. In many cases authorities have to issue so-called NOTAMs (Notice to Airmen).

Laser beams can potentially affect air traffic and distract or impair pilots during flight. So accidential blinding of aircraft pilots has to be avoided under any circumstances. In many countries, severe penalties may apply in case of violations.

Qualified surveillance staff (plane spotters) and additional technical measures, such as ADS-B-based aircraft tracking services or airspace safety scanning devices according to the AS6029 standard, are highly recommended to avoid incidents of such nature.

As one of these suportive measures, LOBO provides an automated aispace surveillance option with position detection by GPS and an ADS-B-based air traffic surveillance system, leading to a fade-out when detected aircrafts enter the saftey zone.
