Protect Employees and Third Parties From Stray Laser Radiation
Most Class 4 and many Class 3B lasers present an eye hazard over very large distances and cannot be allowed to escape from labs or production facilities.  Ordinary curtains or screens are rarely capable of stopping a laser beam, and therefore specially designed curtains are required. Similarly, many production facilities utilize Class 1 lasers which become Class 4 lasers when in production mode (in service).  These lasers require ceiling mounted curtains or freestanding screens made from a suitable material to allow other work to safely continue in the same room during service.

To fulfill protection needs, Lasermet manufactures laser guards made from a special laser blocking, fire proof material which can be supplied off the roll, or as ready made ceiling or wall mounted curtains, roller blinds, window blocks or free standing screens. We believe that these are the highest quality and most cost effective laser guards available in the US.  These are designed for use as passive guards to enclose an area where Class 3B or Class 4 lasers are in use to protect against accidental exposure to the laser beam, or for long term blocking of laser radiation at lower power densities. The material is fire proof. When irradiated with greater than 0.5 MW/m2 it will emit a non-hazardous smoke and may glow, thus indicating that a stray beam is present. Protection times given by the material at various power densities are shown in the specification on the right.
