Laser Curtains

Safety is one of the highest priorities when dividing a large room into individual work areas. PL Systems Inc. curtains use a Modacrylic material as a major percentage of the curtain content. In addition to Modacrylic Self Extinguishing Fabric, SEF, (38%), our curtains contain Saran Flat Monofilament, (30%) for curtain strength, Viscose Rayon (26%) for softness and Polyester (6%) to prevent wrinkles. The back side of the curtain made of vinyl to prevent light penetration.

The properties of this material lend itself as an ideal product to be used in many Laboratories such as Laser Labs Class I-IV  Darkroom/Blackout applications,  Infra-Red, Ultra-Violet Measurement, Gene Separation Silver Halide and many others.

The threshold limit for the beam penetration through the curtain at the minimum distance indicated on the drawings shall not be exceeded for an exposure time of 60 seconds. No part of the installation shall be flammable or support combustion. No part of the installation shall release toxic fumes following a laser exposure. The system shall meet the ANSI Z136.1 Safe Use of Lasers.

Curtain is custom designed to the width of the opening permitting movement of curtains in either direction of the track. The outside vertical edges of each curtain are supplied with “Velcro” quick seal strips to facilitate “light-trap” overlaps for easy attachment to walls. The curtain panel shall be sewn flat plus 10% fullness.  The seams shall be sewn French-style (No raw edges visible).  The top of the curtain shall have grommets on 8″ centers.  The bottom edge shall be weighted and overlap with floor approximately 2” to maintain a light tight environment.

Valance curtain section supplied with front and rear light-trap. The valances shall be a height of 11 inches made of the same as the curtain material with a sewn-on Velcro strip and shall be designed to be mounted to the curtain track assembly.

Track The track is constructed of satin anodized aluminum designed for surface mounting, and to the underside of the ceiling.  The track is extruded aluminum box-channel 1-1/4″ x 7/8″ slotted on the underside to receive two-wheeled carriers.  The track also serves as an integral part of the valance assembly. Fastening should be made not more than 18″ on centers.  Corners, where required, are supplied as one piece, 12″ radius 90-degree track sections.  Tracks are supplied, as required, with hook carriers, end caps, snap-outs, and connectors, of the sleeve type.
