Laser Safety Barrier and Curtain Buyer's Guide

Laser Safety Barrier and Curtain Buyer's Guide

Published by The Laser Safety Experts on May 24th 2021

When purchasing a laser barrier, for the most economical outcome 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: 

Power or energy is known from the following:

  • Power or energy of beam
  • Type of wavelength (CW, pulsed)

To do so, the following parameters can be helpful:

  • Shape of the beam
  • Angle divergence
  • Distribution of the beam
  • 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).  For more information on laser beam parameters, see here.

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 by a free-standing polls or to the ceiling.  

Laser Safety Curtain Option

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

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

Hardware - Barriers

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

The higher the wattage of protection, the more the fabric will cost - which is why we try to work with clients to satisfy the laser safety requirement for protection at the most economical outcome.  The worst-case scenario can also be presumed if information is not known (also common).

Fabric is priced per square foot.
