ScreensCE Marked Laser-Blocking Screens

Portable laser blocking screens

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).

家里没人半夜就和姐姐The main types of certified laser blocking screens (all certified to IEC/BS EN 60825-4) are:-

  1. The LaserLightScreen – the latest, low-cost, floor-hugging, certified, laser blocking, wheeled screen
  2. The Standard Laser Blocking Screen – made using Lasermet’s specially developed laser blocking material
  3. The Flatfoot Laser Blocking Screen – designed to eliminate trip hazards
  4. The Heavy Duty Screen – for multi-kW lasers

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.


These lightweight laser blocking, portable screens are designed to enclose an area where Class 3B or Class 4 lasers are used to protect against accidental exposure or for long term blocking of laser radiation at lower power densities.

  • High Quality

    Designed, manufactured and CE marked to conform to EN 60825-4 using high quality materials and design

  • High Performance

    Blocks all wavelengths – including high power lasers in accordance with EN 60825-4 (Safety of Laser Products Pt. 4 – Laser Guards)

  • Low cost

    These certified laser blocking screens are very well priced for affordability

  • Floor hugging

    At just 5mm above the floor, these screens provide you with proper laser protection all the way up to 2m high. There is also a 2.5m high option.

  • Push to place

    Easy to position and move by just one person

  • Modular design

    Professionally designed interconnectors ensure your safety even in between screens

  • Options

    • Black surfaces or white surfaces
    • 2.0m or 2.5m high screens
    • With wheels or without wheels
  • Flatfoot option

    The Flatfoot option eliminates trip hazard and is suitable for locations where wheels are not required.

Irradiated Area PEL (T3) 10s PEL (T2) 100s
4mm² 150 MW/m² 87 MW/m²
2000mm² 1.2 MW/m² 0.7 MW/m²


Flatfoot Laser Blocking Screens

家里没人半夜就和姐姐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.

家里没人半夜就和姐姐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.

  • Blocks all laser wavelengths

    Up to high power lasers (see specification)

  • CE marked and certified

    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

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 310 MW/m² 170 MW/m²
2000mm² 1.8 MW/m² 1.0 MW/m²

Standard Laser-Blocking Screens

These are available in two standard size screens. The LBS-8 is 2.44 m (8 ft) wide and the LBS-4 is 1.22 m (4 ft) wide. Both are 1.92 m (6 ft 4 in) high, which is high enough to protect the eyes of anyone less than 6 ft 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.

家里没人半夜就和姐姐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.

家里没人半夜就和姐姐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.

家里没人半夜就和姐姐The material is fireproof. When irradiated with greater than 0.5 MW/m2 it will emit a non-hazardous smoke and may glow, thus providing a warning that a stray beam is present

Protection times given by the material at various power densities are shown in the specifications below.

家里没人半夜就和姐姐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.

  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

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 2.37 m wide and the LBS-HD-4 is 1.22 m wide.

The screens consist of a 50 mm 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.

Heavy-duty screens can be used to block lasers of all wavelengths. They offer protection to the following specifications:

Irradiated Area PEL (T3) 10s PEL (T2) 100s
4mm² 62 MW/m² 35 MW/m²
2000mm² 3.1 MW/m² 1.7 MW/m²

Where a production line uses a Class 4 laser for cutting and welding, it is impractical for the whole facility to observe Class 4 safety regulations. However, using complete enclosures can to turn the laser facility into a Class 1 system.
