To protect personnel from Class 4 and Class 3B lasers it is imperative to have comprehensive laser safety protection in place. Laser radiation must be prevented from escaping from labs and manufacturing facilities using certified equipment. Also, facilities utilising Class 1 lasers which are Class 4 under service conditions may require free-standing screens to allow other work to continue safely in the same room during service.
Lasermet provide a range of free-standing laser-blocking screens which are designed for use as passive guards to enclose areas where Class 3B or Class 4 lasers are in use either to protect against accidental exposure to the laser beam or for long term blocking of laser radiation at lower power densities. All Lasermet laser-blocking screens are CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards).
The three main types of certified laser blocking screens (all certified to IEC/BS EN 60825-4) are:
The Standard laser blocking screen
The Flatfoot laser blocking screen and
The Heavy-duty screen
All of the screens are portable and can be used as simple temporary installations or can be used on a semi-permanent or permanent basis as required.
Standard laser-blocking screens
These are available in two standard size screens. The LBS-8 is 2.44m(8ft) wide and the LBS-4 is 1.22m(4ft) wide. Both are 1.92m(6ft4in) high, which is high enough to protect the eyes of anyone less than 6ft 8 inches tall standing right up to the screen, while low enough to pass through a standard doorway.
The screens can be made higher if desired. Standard laser-blocking screens use the same specially-designed laser blocking material used for laser blocking curtains and screens. The material is mounted on a black powder coated steel framework, supported on lockable castors. The laser-blocking material, which seals to the floor, is white on one side and black on the other side. It will operate as a blackout screen as well as a laser-blocking screen.
Both sides will block laser radiation but if the white side is used as the laser-blocking side a higher specification of blocking will be achieved, making it suitable for higher power lasers. The material is fireproof. When irradiated with greater than 0.5MW/m2 it will emit a non-hazardous smoke and may glow, thus providing a warning that a stray beam is present.
Standard screens can be wheeled easily into position and then kept there by locking the castors. Multiple screens can be connected together using connecting pieces (LBS-C) in a straight line or at an angle up to 90 degrees. If four or more screens are used an enclosing rectangular enclosure can be constructed.
Flatfoot laser blocking screens
These lightweight, Flatfoot laser blocking screens are designed as a semi-permanent passive guard to enclose an area where Class 3B or Class 4 Lasers are in use, to protect against accidental exposure or for long term blocking of laser radiation at lower power densities. They provide a cost effective and easily-installed, high-quality professional solution to your laser blocking requirements.The screens are designed to block all laser wavelengths including high power lasers.
Benefits of the Flatfoot laser blocking screens include:
Blocks all laser wavelengths - up to high power lasers
CE marked and certified to provides laser safety protection to IEC/EN 60825-4 (Safety of Laser Products Part 4: Laser Guards)
Quick and easy to install: two people can install and manoeuvre the screens into place to provide a rapid-build laser enclosure
Modular: further screens can be attached to extend or change the enclosure, providing a flexible approach to installations, facilitating potential relocation or expansion
Heavy-duty laser blocking screens
These screens are designed to block all lasers, including high power, multi-kilowatt materials processing lasers. There are two standard size screens, both of which are 1.98m high. The LBS-HD-8 is 2.35m wide and the LBS-HD-4 is 1.185m wide.
The screens consist of a 50mm thick sandwich of steel and a special lightweight laser-blocking material, with a white laminate finish on both sides. This is mounted on a powder-coated steel framework, with heavy-duty lockable castors. The screens can be wheeled into position and then kept there by locking the castors. They can be used to form a complete enclosure or part thereof.
