Large Area Chemical Security

Block Engineering's LaserWarn is an open-path chemical detection system based on patented quantum cascade laser technology. LaserWarn detects chemical threats, leaks, and fugitive emissions over a coverage area of thousands of square feet, and can be used in both indoor and outdoor applications.

Eye-safe laser beams and low-cost retroreflectors provide real-time, 24/7 early warning of Toxic Industrial Chemicals (TICs), Chemical Warfare Agents (CWAs) and other chemicals. Any target gas crossing the lasers, even at low concentrations, will be detected with a sub-second response time. The system requires no consumables, and is low maintenance compared to conventional networks of point sensors.

Both fixed-site and portable configurations are available. In fixed-site installations, the LaserWarn is positioned with mounted mirrors and retroreflectors to cover large areas, including perimeter monitoring of facilities. Portable configurations allow the LaserWarn to be brought to the boundary of a "hot zone" while reflectors are safely introduced to scan for chemical contamination.

Unlike conventional open-path IR and FTIR systems, the LaserWarn is able to detect chemicals at great standoff distances (standard range of 500 meters, with extended ranges of up to 3 kilometers). The system requires no liquid nitrogen or other consumable cooling mechanism. An extremely wide range of gases are detectable, and at a weight of 5 kilograms, LaserWarn can be easily relocated and reprogrammed for rapid detection of new threats.
