Laser protection systems
High-tech solutions for high-tech applications
Laser protection systems offer the necessary protection for man and machine in all situations.
When it comes to laser protection, we differentiate between passive and active solutions. Passive laser protection generally enables short-term protection against laser radiation. Passive laser protection solutions were an adequate solution, especially at the beginning of the laser age. This still applies to lasers with low power or to some applications in the observed operation.
In recent years, however, the available laser power has increased so much that passive laser protection solutions are reaching their limits.
JUTEC GmbH has recognized this trend and is offering active textile laser protection solutions for the first time - tested for high-power applications up to 12 kW laser power.
What do we mean by active laser protection?
The textile, multi-layer laser protection structure ML-20 contains a sensor layer. This sensor position is looped into the safety circuit of your laser system via measuring electronics. If the system breaks down and the laser beam is focused on the protective device, it switches the laser off.
Our active laser protection system is particularly user-friendly and easy to install. You can currently find it in the following of our products:
- Active system protection
- Active laser safety curtains
- Active laser protection swivel arm frames
- Active laser protection walls.
The active laser protection system also offers you the option of RetroFit - your existing, passive laser protection cabin is simply activated within a very short time - if desired, only locally where it becomes critical and the passive protection does not offer any safety.
Active system protection
For fully automated 2D or 3D laser processing systems.
Fully automated systems must have a switch-off device so that exposure to laser radiation cannot occur even in the event of a breakdown in the system. An accident occurs, for example, when the machining process is unintentionally interrupted while the laser cannot be switched off; a mirror in the beam guidance fails, so that the laser beam leaves the planned beam path.
In this case, the active laser protection system offers the necessary protection by being positioned at the points where the laser beam can potentially hit. In the event of a mirror break (e.g. due to mechanical damage), the laser beam hits the active laser protection textile and the laser is switched off.
Active laser protection for fully automated 3D robot systems.
Active laser protection textiles can also be used in the enclosures of laser processing systems. This is particularly useful if it is a fully automated 3D processing system and the laser beam can hit the walls of the housing in the event of an accident or unplanned destruction of the workpiece by the laser.
- Assembled according to the space requirements of your system
- Local equipment of particularly endangered areas
- Competitive advantages for you and your customers
- Shutdown of the laser source by opening the safety circuit
- Simplified acceptance of the processing system; Take active laser protection textile into account during construction
Retro fit
With an active laser protection system, for easy retrofitting of your laser cabin.
If you want to convert your machining process from a CO2 laser to a modern fiber or disk laser, or if you simply use a more powerful laser, the requirements for laser protection increase considerably.
Retrofitting your laser cabin with the active laser protection textile eliminates the need for a new building or costly retrofitting of the cabin, as particularly endangered areas can simply be retrofitted with the active laser protection textile. In the event of laser bombardment, e.g. due to a system failure, the active laser safety curtain switches off your beam source - the dangerous situation is over. We adapt the dimensions of the active laser protection textiles to your needs.
Of course, JUTEC offers the complete retrofitting - starting with the consultation, the adjustment of our system using the most modern CAD software, the installation and the acceptance by an expert so that the CE of your system is retained. Retrofits usually take less than 1 working day, so you hardly have any downtime in your system.
Mobile laser safety cabin
Limitation of the laser area and protection of surrounding employees.
Mobile (hand-held) laser devices are now so flexible that they can be used in almost any production environment. The size of the laser device allows the laser to get to the workpiece and not the other way around. It is now time to provide laser protection that is just as mobile and flexible as the laser source.
The mobile laser cabin - which is available in both active and passive versions - helps you to delimit the laser area so safely that surrounding employees are not restricted in their activities by working with the laser. In accordance with the modular design of the cabin, roof modules are optionally available so that the laser area is protected from all sides. This is particularly important in high, spacious halls, when not all entrances (e.g. on galleries) can be locked.
The cabin can be equipped with the active laser protection system ML-20 or the passive laser protection textile ML-6.
Dimensions: height 2250 mm, module width 1100 mm (other dimensions on request). The proven size is 3 x 3 modules. Interior space approx. 3300 x 3300 mm²

With active laser protection, you also protect mobile and stationary laser systems with outputs of up to 12 kW. The combination of the passive laser safety curtain ML-20 and the mobile swivel arm frame on castors is ideally suited for temporary laser protection in mobile laser applications. In order to be able to protect your application in the best possible way, different heights and widths are available as standard.

Laser safety curtain
Passive laser safety curtain to protect laser areas in laboratories and medical facilities.
The multilayer protective curtain ML-6, consisting of diffuse reflective and non-flammable fabric, is suitable around laser areas in laser classes 3B, 3R, 4 or 1.
NEW 2021: Also available as a variant ML-6-2 that can be used on both sides.
The suitability of the laser safety curtains for the respective application is subject to the individual examination of the laser specifications and is the responsibility of the laser safety officer on site. We would be happy to support you in this. As a light-tight material, the curtain is suitable for laser wavelengths from 200 to 11000 nm in the medium power range and is certified according to the DIN EN 12254: 2012-04 standard for shielding at laser workstations.
Equipment:
