Laser Safety Barriers and Curtains

Energy Intensity Equation

When purchasing a laser barrier, it is important to understand the Energy Intensity of the beam at the distance from the laser it is intended for. Energy intensity is calculated using:

Power or energy of beam

Type of wavelength (CW, pulsed)

Continuous Laser

Pulsed Laser

To do so, the following parameters can be helpful:

  • Beam shape
  • Angle divergence
  • Beam distribution
  • Whether or not the beam is focused or not

We've included a few images displaying beam shape (corresponding to area) and beam divergence (area expands as distance increases from the beam).

We give complimentary laser safety consultations and often can scope down the requirement for the laser safety barrier and saving our clients upwards of 30%.

How Quoting/Pricing is Done for Custom Laser Barriers and Curtains

Fundamentally, there are two components: hardware and the fabric

Hardware - Curtains

Curtains have two options, to either be attached to free-standing poles or to the ceiling.  

Laser Safety Curtain Installation

If the curtain is to attach to a wall, a peelback adhesive strip is used.  

Adhesive To Wall

For both curtains and barriers, if desired a divider can be applied to connect or re-configure any laser barrier system.

Middle Connector Strip

Hardware - Barriers

Barriers can either have casters (wheels) or be stand-alone.

Hardwall Systems


The higher the wattage of protection, the more the fabric will costwhich is why we work with clients to satisfy the laser safety requirement for protection at the most economical outcome. When in doubt, opt for the highest form of protection.  

200W and 300W

Fabric is priced per square foot and is stated as the maximum irradiance is 200W/cm^2 or 300W/cm^2 with a beam size of 5mm for 100 seconds.
