Active Enclosure
Active Laser Safety Cabin
Lasermet’s Active Enclosures is a laser safety cabin fitted with active guarding system – Laser Jailer. These modular, Class 1, room-sized enclosures are tested and certified to international laser safety standards and can be rapidly designed, built and installed by Lasermet.
- Rapid-build modular laser safety cabin
- Class 1 enclosure for Class 4 lasers
- Active Guarding System has fail-safe laser detection technique
- Suitable for all laser wavelengths
Description
The laser safety cabin comprises of panels constructed from laser safety compliant material and fitted with Laser Jailer® Active Laser Guarding System. This patented modular system has active detector panels covering the internal walls and roof of the cabin to detect high powered laser beam strikes. If this occurs, Lasermet’s fail-safe technology isolates the laser safety input in less than 50ms and laser operation is terminated until all safety interlocks are reset. These Active Enclosures is supplied with Lasermet’s Interlock® Control System which includes LED Warning Signs, Interlock® Controller, Interlock Switches and Door Maglocks, Audio Alerts (optional), and HD CCTV System (optional).
The Active Guarding System is effective against all laser wavelengths and particularly with high power laser of 1kW and more.
Application for Active Enclosure
Active Enclosures is an effective laser containment system ideal for industrial laser applications, such as aerospace, automotive and energy industry . It is also a safety consideration to contain lasers in applications that use laser additive manufacturing of complex parts and additive welding.
This high speed active laser safety control system prevents laser destruction of surrounding infrastructure. This includes preventing damage from laser beams to the building and its services. The Laser Jailer is much more than a simple beam blocking barrier, its fast response is achieved by sensing the laser impacting on the active laser wall within the laser room. If a stray laser beam impacts on one of the tiles, the Interlock® will isolate the laser safety input in less than 50ms. The laser will be turned off – the precise shut-off time being dependent of the laser machine in use.
Compliance and Safety Standards
The system is certified for and conforms with:
- BS EN IEC 60825-4: Safety of Laser Products Part 4 – Laser Guards
- EN IEC 60825-1: 2014 Safety of Laser Products Part 1: Equipment classification and requirements
- Machinery Directive
- Low Voltage Directive
- Electromagnetic Compatibility Directive
PEL Ratings
The enclosure panels are available in two different thickness – 50mm and 100mm. The PEL ratings for the panels are listed below.
| Panel Thickness | Irradiated Area | PEL (T3) 10S | PEL (T2) 100S |
| 50mm | 4 mm² | 150 MW/m² | 87 MW/m² |
| 2000 mm² | 3.1 MW/m² | 1.7 MW/m² | |
| 100mm | 4 mm² | 310 MW/m² | 170 MW/m² |
| 2000 mm² | 5.1 MW/m² | 3.0 MW/m² |
Passive Enclosure Option
A passive laser safety cabin is also available for laser power of less than 1KW (< 1KW). Lasermet’s Laser Castle is built from from passive laser safety compliant material and certified to the Laser Safety Standard EN IEC 60825-4. The panels are connected together (including a roof) to form the enclosure. Provision is made for fume extraction systems and a lighting package, making this a cost effective and extremely easy method of enclosing the laser system to comply with international laser safety standards.
Ordering Options
To specify the Active Enclosure System you require, the following items must be addressed.
- Specification of the laser
- Intended use of the laser
- Dimensions and specification of the laser safety enclosure – a large laser enclosure may need estimated measurements for quotation purposes
- Identification of relevant safety interlocks -doors, switches, maglocks.
Lasermet are happy to assist if you would like to know more about the system and we can arrange for a site visit if you are unsure of the level of safety you require.
