How It Works

This tool will help you find the laser barrier curtain that works for your laser. To find the best material for your laser application, you'll need to gather the following details about the laser device and how it will be used (including descriptions). We have included the guide below that will help you gather the necessary details to use the tool. If you are having trouble or are unsure, consult your Laser Safety Officer (LSO) before making your final material choice. If asked, sample materials can also be sent for testing and review.

 

Where to Look

The Power Output

This is the amount of energy that the laser beam gives off every second. It is usually given in watts (W), kilowatts (kW), or milliwatts (mW).

There is a label on the housing, a user guidebook, the manufacturer's website, or the software interface of the machine where you can find this information.

Wavelength

The number of nanometers (nm) it has tells you what kind of light it gives off, like visible, infrared, or ultraviolet. The wavelength is often found in the same places as the total power. Look at this example:

 

Direct and diffused laser beam comparison showing light spread difference by AKON

Beam

A laser's beam type, whether it's diffused or direct, shows how the light is sent out, how it spreads, and how it hits the screen.

  • Direct Beam: Narrow, focused, and very strong. Used for engraving, cutting, and making points.
  • Diffused Beam: Spread-out, low intensity. Used in scanners, laser levels, alignment tools.

Gather Your Data

Understand the Application.

  • Direct Beam:
    • The laser beam can hit the curtain or obstacle straight on.
    • Needs materials that can handle direct beam contact.
  • Diffused Beam:
    • The curtain can only be lit by reflections or lights that are spread out.
    • It can be used with products that are rated for diffused exposure.

Look at the laser label or the guide.

  • Look for words that describe beam types:
    • "Collimated": Indicates a direct beam.
    • "Divergent": Indicates a diffused beam.

Look over the Beam Divergence data sheet.

  • Beam divergence can also be an indicator.
    • Low divergence (<2 mrad): Direct
    • High divergence (>10 mrad): Diffused

Check things visually (if needed)

  • Look at where the laser beam is on a surface:
    • Clear and sharp dot: Most likely direct
    • A long glow or line: Probably spread out

Tip for Buyers: If you're not sure which material to use, talk to the laser manufacturer or supplier with your beam specs.

Models

Laser Barrier Curtains

Commonly used for laboratories, security rooms, dermatology, research & development facilities, veterinary, and electronics manufacturing facilities, the laser barrier curtains are made for heavy-duty use.

Retractable Laser Panels

The SB-9000 Retractable Laser Screen is designed with a retractable system that extends up to 20 feet in length and automatically retracts with a spring tension roller.

Laser Barrier Covers

Laser barrier covers can be used for openings like windows and doors. Made from the same material as the laser barrier curtains, these covers are easy to install and are very effective.

 

Portable Laser Curtain Barriers

These portable curtains are used for hospitals, surgical rooms, labs, and manufacturing facilities. They offer a laser barrier protection up to 575 W/cm2 Tested at 1064nm with 1mm beam diameter.

Foldable Laser Panels

These foldable curtains are used for hospitals, security rooms, labs, and manufacturing facilities. They offer protection against accidental exposure to hazardous radiation and reduce the risk of injury.
