Laser Protection with Laser Safety Curtains
Installing certified laser blocking material is necessary to guarantee that Class 4 and Class 3B laser beams do not escape from laser laboratories or medical facilities, such as hospital theaters. It is rare for regular curtains to stop a laser beam; instead, one needs to use specially designed, certified laser blocking material.
Designed to enclose a laser-using area passively, either to prevent accidental exposure to the laser beam or to permanently block laser radiation at lower power densities, laser curtains serve as protective barriers.
Lasermet’s Laser-Blocking Curtains are ready-made ceiling or wall-mounted curtains made from the company’s specially developed laser blocking material.
The Orca material operates as a blackout screen as well as a laser-blocking screen and is available in several colorways:
- White / Black
- Black on both sides
For smooth operation, heavy duty curtain tracks can be supplied. High-quality cubicle curtain track is available for applications where the curtain must be suspended below the fixing points.
MOTORISED LASER PROTECTION CURTAINS
Lasermet’s laser blocking curtains can be motor powered up to a maximum run of 10m (32.8 ft) or 60kg (132.2 lb).
High Specification Safety
Lasermet laser-blocking Orca products are CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards).
Tested in accordance with NFP 92-503 (Electrical Burner Test), the material is rated as M2. When irradiated with greater than 0.5 MW/m² it will emit a non-hazardous smoke and may glow, thus indicating that a stray beam is present.
Laser radiation protection times given by the material at various power densities are shown in the specifications below.
| Irradiated Area | PEL (T3) 10S | PEL (T2) 100S |
| 4mm² | 3.9 MW/m² | 2.2 MW/m² |
| 2000mm² | 0.62 MW/m² | 0.35 MW/m² |
DIRECTIVES AND STANDARDS
- Machinery Directive 2006/42/EC
- EMC Directive 2004/108/EC
- BS EN IEC 60825-4 Safety of Laser Products, Part 4: Laser Guards
