Lasermet laser-blocking Orca products are CE marked and certified to EN 60825-4 (Safety of Laser Products Part 4: Laser Guards).
Lasermet’s Laser-Blocking Curtains are made from the company’s specially-developed laser-blocking material and are supplied ready-made as ceiling or wall-mounted curtains. The material is white on one side and black on the other side and will operate as a blackout screen as well as a laser-blocking screen. This material is branded as Orca.
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|
|Black or White Side||4mm²||3.9 MW/m²||2.2 MW/m²|
|2000mm²||0.62 MW/m²||0.35 MW/m²|
The top of the curtain has brass eyelets every 150 mm and the curtain is supplied with a stainless steel hook for connecting to a curtain track. The weight of the material is 1.3 kg/sq m. Heavy duty curtain tracks can be supplied for smooth operation. For applications where the curtain needs to be suspended below the fixing points, high-quality cubicle curtain track is available.

Q. CAN YOU USE ORDINARY BLACKOUT CURTAINS TO STOP LASERS?
A. No. Conventional curtain material is not good enough. It will not have been tested and it is usually made from a mesh or it will be woven. Either way it will have small gaps. It is also unsuitable material as the laser could easily burn through it, set fire to it, or simply pass straight through causing irreparable damage to skin or eyes. Lasermet’s laser blocking material is tested and is certified to conform to the stated PEL (Permissible Exposure Limit) ratings listed in the respective tables.
Q. CAN I USE ANY BLACK PLASTIC MATERIAL TO STOP THE LASER LIGHT?
A. No. Plastic material may reduce daylight but it not suitable for lasers. Laser protective material must be tested and certified as conforming to the laser safety standard BS EN IEC 60825-4.
Q. WHICH LASER BLOCKING MATERIAL IS SUITABLE FOR SUN BLOCKING?
A. Either of the options are suitable for sun blocking: the “Orca” (Black and white range) or the grey “Wolf” range.
Q. ARE THE CURTAINS LIGHT-TIGHT AND SUITABLE FOR A DARK ROOM?
A. No. Laser blocking material is designed to stop direct laser light. Diffuse sunlight or ambient lighting may be reflected around the edges of roller blinds or curtains.
