Laser Safety Barriers and Curtains

Laser Safety Industries manufactures laser safety barriers and curtains designed to support ANSI Z136 laser safety programs by helping contain hazardous laser radiation and protect personnel.

Our portable and stand-alone barriers support temporary and permanent laser safety setups, while our curtains can attach to floors, walls, ceilings, and custom frames for industrial, medical, research, and manufacturing environments.

Available in standard and custom configurations, our barriers and curtains provide durable, reliable containment for laser applications including Nd:YAG, CO₂, Er:YAG, UV, visible, and fiber laser systems.

Why Laser Power Alone Does Not Determine Barrier Selection

Laser barriers and curtains are often mistakenly treated as though they are intended to serve as a target for a continuous direct beam exposure (as this is how we test and rate them). In many applications, they are instead used to contain reflected, scattered, or diffused laser radiation around a controlled work area.

In many applications, laser energy reflects, scatters, diffuses, and spreads through the work area before reaching the barrier or curtain. The expected irradiance at the containment material is often the key factor in selecting an appropriate system.

1. Laser Energy Can Diffuse Through the Work Area

Laser energy can reflect, scatter, and diffuse through the work area before reaching the containment boundary.

2. Irradiance Drops as Energy Spreads

As laser energy spreads over a larger area, the irradiance reaching the containment boundary can be much lower than the concentrated energy near the source.

3. Barriers Contain the Controlled Area

Laser barriers and curtains are often mistakenly evaluated as though they are intended to absorb a continuous direct beam exposure. In many applications, they are instead selected based on the reflected, scattered, or diffused laser energy expected to reach the containment boundary.

Laser safety products should always be selected based on a complete hazard evaluation. Final containment selection should be reviewed by a qualified Laser Safety Officer (LSO) or laser safety professional.

Standards & Compliance

Our laser barrier and curtain systems are designed to meet or exceed applicable laser safety requirements for use with appropriate laser systems.

Laser Safety Industries manufactures laser safety barriers and curtains using materials that meet or exceed NFPA 701 standards and use FM compliant material FM4950.
