BEAMSTOP'R Laser Barriers

BEAMSTOP'R Laser Safety Curtains confine a laser's beam, ensuring a safe working environment for technicians in laser spectroscopy laboratories and other facilities. BEAMSTOP'R Laser Safety Curtains are the perfect Laser Barrier for hospitals as well as for medical and dental offices.

BEAMSTOP'R Laser Safety Barriers protect workers against the accidental and chronic occupational eye and skin exposure that results from reflective laser radiation and broadbent optical radiation generated by laser plume.

BEAMSTOP'R Laser Safety Curtains conform to recommendations of national industry standards. As the American Nationals Standards Institue reports in publication 4.6.2, "...Enclosure of the laser equipment or beam path is the preferred method of control, since the enclosure will isolate or minimize the hazard."

We are the only LASER SAFETY company that has a medical consultant on staff to address the unique requirements of a Dental Office, Medical Office, Laser Clinic or Hospital. Use our contact form to find the best method of setting up Laser Safety Curtains so that they provide safety, in a practical, cost efficient manner.

There is no current national standard for the measurement methods for such penetration threshold levels. There has been recent recommendation that the ANSI Z-136 committee consider establishing a separate standard on Laser Protective Equipment. One mission of such a new standard would be to recommend a measurement protocol for laser protective equipment (e.g. eye-wear, window filters and protective barriers).

While meeting your facility's budget is always your concern, we can custom design BEAMSTOP'R Laser Safety Curtains in any width or length, on conventional tracking or in panel systems. All BEAMSTOP'R Laser Barrier products are sewn with double- and triple-reinforced seams, and are available in black or white.

BEAMSTOP'R Laser Barriers have been tested and proven to be an effective barrier for:

Nd:YAG, excimer and CO₂ lasers
laser radiation from the ultraviolet to infrared

BEAMSTOP'R Laser Safety Curtains have exceptionally high damage thresholds. They can withstand:

28 MW/cm² of Nd:YAG fundamental (1064 nm); over 600 laser strikes of 100mJ/pulse
14 MW/cm² of Nd:YAG second harmonic (532 nm); over 600 laser strikes of 50 mJ/pulse
4 MW/cm² of KrF eximer laser (248 nm); over 600 laser strikes of 100 mJ/pulse
80 MW/cm² of CO₂ laser (10600 nm)' over 10 laser strikes of 400 mJ/pulse

As the scope of laser controls more frequently include an area barrier as a means of either temporary or permanent protection, it becomes important to determine if the barrier can provide the protection that is needed. Simply stated...will the barrier withstand the laser beam long enough - without penetration - so that the operator can turn off the laser or take other actions to avoid the beam?

The ANSI Z136.1 standard [1] recommends (see section 4.6.4):

Laser Protective Barriers and Curtains (Class 3b or Class 4).

A blocking barrier, or screen, or curtain which can block or filter the laser beam at the entryway should be used inside the controlled area to prevent the laser light from exiting the area at levels above the applicable MPE level.

Such laser barriers shall be specifically selected to withstand direct and diffusely scattered beams. In this case, the barrier shall exhibit a damage threshold for beam penetration for a specified exposure time commensurate with the total hazard evaluation for the facility and specific application. (See Z136.1 Appendix C).

Important in the selection of the barrier are the factors of flammability and decomposition products of the barrier material. It is essential that the barrier not support combustion or release toxic fumes following a laser exposure.
