Lasermet Ltd

Lasermet is a world renowned leader in laser safety, having been heavily involved in the development of the internationally recognised laser safety standards IEC / EN 60825 for many years. 

Lasermet is privately owned and is a ISO 9001 registered company. It was founded in 1987 and has been providing laboratories, hospitals, clinics, manufacturing facilities, universities and many other institutions with all of the laser safety expertise in terms of products and services needed to ensure laser operators, staff and other personnel are kept safe from the potentially damaging effects of laser radiation.

Lasermet’s vast experience in laser safety puts it in a strong position - worldwide - to define and produce laser safety products and services that meet the laser safety standards’ criteria. 

As a result, Lasermet designs, manufactures and installs an extensive range of products covering all aspects of laser safety, notably laser safety cabins for high powered lasers, laser interlock control systems, laser blocking curtains, screens and roller blinds.

Lasermet's headquarters are in Dorset, and the company has overseas offices in Illinois in the US.  The company has a Manufacturing Centre and R&D Development Facility located in Haydock near St Helens, Merseyside, and in addition Lasermet is represented worldwide by a network of Distributors.

Fraunhofer CLA choose Lasermet's Laser Castle for laser safety

Fraunhofer CLA choose Lasermet's Laser Castle for laser safety

Fraunhofer is Europe’s largest application-oriented research organization with locations throughout the world and Fraunhofer CLA has been operating in the USA since 1994 developing new laser applications for a wide range of industrial customers. With its extensive expertise in laser materials processing and a state-of-the-art laser facility, the Fraunhofer USA CLA team helps to develop best process solutions including laser welding, laser cutting/drilling, laser cladding, and laser heat treatment. Fraunhofer’s facilities include Robotic and CNC work cells with fiber, disk, diode and CO₂ lasers up to 16kW and a state-of-the-art Metallographic Lab.

The laser safety cabin’s main double-doors open to 10ft (3m) wide and are 10ft (3m) high to accommodate large pieces of equipment. The cabin is certified as laser safe (as required by the laser safety standards within IEC 60825-1 and ANSI Z136.1), and is interlocked with a fully dual-channel interlock control system. Fitted with High Definition CCTV and an HD monitor, an additional interlocked access door and dual-message, dual-colour LED Laser warning signs, the Laser Castle provides the complete solution.

Active Laser Guarding - “Laser Jailer”
As lasers up to 16kW are used, the only failsafe way to ensure the safety of personnel outside the cabin is to shut down the laser if an inadvertent laser strike occurs. This is achieved by covering the inside of the cabin with active laser guarding panels which are electrically connected to the interlock controller. These panels are constantly monitored by the interlock controller and if any of these are struck by the laser, the controller isolates the laser safety input within 50ms, shutting down the laser virtually immediately and preventing the escape of the beam into the surrounding area. In addition to the passive and active guarding provided by the cabin, the manual doors have two Active Guarding Filter Windows (called “Glaser Jailer”) and these are also linked to the laser interlock controller (ICS-6) in the same way as the rest of the active laser guarding system. They work in the same way. If the windows are struck, the controller switches off the laser virtually immediately. Fraunhofer CLA works in close co-operation with the Fraunhofer Institute for Material and Beam Technology (IWS) in Dresden Germany, one of Europe’s leading research institutes for laser material processing.
