infinity beam®

With the success of the sparks series, LOBO has proven to build the world‘s brightest multi-color entertainment lasers. The new infinity beam projectors takes anything, which made sparks so successful, to the next level.

Unlike any other entertainment technology, the brilliant beam of an infinity beam projectors pierces trough the night sky for dozens of miles.

Custom-designed long-range optics and projection heads as well as a moving head base option make infinity beam not only a high-end alternative to regular sky-tracking searchlights with an orders of magnitude increased reach, but also a laser entertainment system for the masses with the lowest possible carbon footprint.

Product overview

An infinity beam® projector can be individualized to any given application by flexible laser configurations and exchangeable display heads, such as beam heads or scanning heads for mid-range and long-range jobs.

Anytime you can decide to add further lasers, to change the display head or to go for the moving base option. So, your infininty beam system exactly adapts to your changing needs on the basis of the existing system and without major re-investments.

Product Features

Three years ago, LOBO pioneered the market with its revolutionary PCS system. This proprietary optical system increased the effective real-life brightness of the most powerful multicolor OPSL lasers by 9 times. For regular show use, infinity beam systems are also available with this projection technique, but with significantly more power and an ultra-sharp single-mode beam (TEM00). For even more demanding applications, infinity beam systems are available with dedicated long-range display heads for aerial beams or projections. 

Their revolutionary multi-stage DSC optics excels LOBO‘s own record-breaking benchmark by means of a completely re-designed and more capable PCS system, which increases the effective brightness on long distances by up to 50 times! This unique combination of world-leading multi-color ouptut power, market-leading energy density and utmost flexibilty of use is the dawn of a new era in large-scale laser entertainment.

Unparalleled long-range brightness

The core of any infinty beam® projector is a photonic engine with up to 4 ultra-high-power OPSL laser modules. Each of these lasers delivers output powers up to 26 W with a reference-quality TEM00 beam, resulting in total max. powers in the 100 W range. But to deliver its unparalleled reach and real-life brightness, just a lot of Watts is not enough.

The effective brightness of a laser system finally depends on the light intensity in the air and on maintaining this intensity over long distances: Twice the power means twice the brightness. But half the diameter of a beam means an increase of approximately 4 times in effective brightness (as the beam shrinks in two directions). So the beam diameter and its divergence have a much stronger influence on the final visibility than just the output power of a laser. Thus, investing money in a better beam makes more sense than investing it in more Watts.

The estabilshed PCS9 system introduced with sparks already reduced the beam divergence by 3 times, resulting in a 32 = 9 times increased effective brightness. The completely new DSC long-range optics inside infinity beam results in a phenomenal increase in brightness on long distances up to 50 times! A laser entertainment system with such specifications changes the whole game and opens new dimensions in entertaining the masses.

Even the brigthtest regular searchlights are looking poor on long distances compared to what infinity beam projectors can do. Crossing distances of up to 60 km suddenly become reality. With the new long-range projection head, infinty beam projectors even deliver convincing results under adverse conditions, such as a high ambient light level or long distances.

A professional entertainment laser without compromises

For regular show use, there is a wide choice of solutions on the market. But when it comes to aerial beams or long-range projections, laser companies always were forced to develop custom-made and sometimes very adventurous individual setups.

Some companies even experiment with industry lasers, originally built for completely different things. But such lasers lack anything you need for show applications. They are bulky and sensitive as they have not been designed for road use, but for controlled industry- or laboratory-degree environments.

Infinity beam® provides an extremely flexible multi-color outdoor infrastructure for long-range applications and giant show performances without any compromises anymore:

  • Compact, flexible, self-sufficient design (no sensitive and bulky half-ton machines, no fibers,...)
  • Easy to install and operate (industry lasers are not made for road use requiring a lot of expertise)
  • Maintenance-free design (industry lasers require regular and very expensive servicing)
  • Completely air-cooled up to 35°C (high-power industry lasers require water cooling)
  • Rigid, weather-proof design (industry lasers are built for controlled, laboratory degree conditions only)
  • Continuous Wave (CW) output for long-distance audience-scanning atmospherics and projections (industry lasers are usually pulsed and not permitted for regular show applications)
  • Multi-color output (industry lasers usually are available in green color only)
  • In spite of lower output powers, a higher beam intensity on long distances thanks to DSC. The following chart compares the typical effective laser brightness of an established 400 W industrial laser, sold for show applications, with the typical values of a 26 W infinity beam system on a distance of 10 km - in spite of a fraction of the output power and the same color, infinity beam is brighter by far:

The following graph compares the typical effective laser brightness of an established 400 W industrial laser, which is also sold for show purposes, with that of an infinity beam system with only 26 W over a distance of 10 km - despite significantly lower power and the same color (green), the infitity beam system is significantly brighter:

The calculations have been effected on the basis of the ELB formula in the LOBO main catalog and the specifications published by the respective manufacturers at the date of pubilshing (15.01.2014). LOBO does not assume any reliability for the correctness of these specifications.

Future-proof modular Design

An infinity beam® projector can be individualized to any given application by flexible laser configurations and exchangeable display heads, such as beam heads or scanning heads for mid-range and long-range jobs. Anytime you can decide to add further lasers, to change the display head or to go for the moving base option. So, your infininty beam system exactly adapts to your changing needs on the basis of the existing system and without major re-investments.

Built for Extremes

Infinity beam® systems are native outdoor projectors. Thanks to their dual-shell stainless steel IP54 housing, they are built for temporary outdoor use without the need for further protective housings. Anything inside is built to handle extreme power densites, which would destroy regular market-standard components immediately. This starts with supreme optical components and ends with especially designed scanning systems.

Advanced Control and Synchronization

DDL-2® controls many independent systems by one optical signal line over large distances, irrespective of weather or electromagnetic interference. A system-inherent safety logic allows the safety monitoring systems of all components to initiate an emergency safety shutdown. All system functions and status monitoring can not only be controlled from the detachable reomote control. but also from the show controller.

Integrated System Design

It takes a lot of expertise and sophisticated cooling systems, to operate long-range laser systems. Usually they require external units, such as chillers with water cooling. LOBO managed to integrate all components, including a cooling system for high ambient temperatures, into an compact enclosure. This allows easy handling, transport, short setup times and a hazzle-free operation.

Free Safety Training and Certification

It takes a lot of expertise handling laser systems of the inifnity beam class in a professional and safe way in accordance to all applicable safety standards. In addition to multi-redundant technical safety measures in each system, LOBO tries to reach a maximum safety standard by including free laser safety training with a certification according to BGVB 2 (VBG 93) for the operators of each system sold.

Safety Remarks

Infinity beam lasers with beam 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. Especially when using Beam Display Heads, users have to take special safety measures.

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.

Examples of use

To give you a better impression of the quality and flexible applications of the products, you can find photos and videos and different application examples here:

infinity beam - Live im Einsatz

Auf 246 m Höhe, auf dem Thyssen-Testturm in Rottweil, wird der Nachthimmel langsam horizontal von einem ultrahellen infinity beam abgescannt. Nahezu majestätisch, im Anschluss einer grandiosen Eröffnungsshow, durchdringt der Strahl des infinity beam mit einer Helligkeit von 44683 W/m² noch über Stunden den Himmel und ist dabei über dutzende von Kilometern weit sichtbar.

infinity beam - Projektvisualisierung

Machbarkeitsstudie zweier auf infinity beam-Technologie basierender Projekte im mittleren Osten. Eine Visualisierung der technischen Konzeption in Form eines computergenerierten Videos. Da der infinity beam nicht nur wetterfest und als ultraheller Laser für extreme Distanzen entwickelt wurde, sondern sich zudem auch noch individuell konfigurieren lässt, können mit diesem Laser unterschiedliche Projekte realisiert werden. Beispielsweise kann er in einer statischen Single Beam-Version als 'Richtungszeiger' nach Mekka für eine Vielzahl von Moscheen genutzt werden, da sich unzählige infinity beams über jede beliebige Distanz synchronisieren lassen; alternativ, gezeigt am Beispiel des Burj Khalifa, als Moving Single Beam-Version - oder, wie ebenfalls visualisiert, mit einem Projection Display Head für unzählige bewegte Strahlen. So oder so: durch den infinity beam kann ein Gebäude zum weithin sichtbaren Blickfang werden.
