Coherent PowerLine High-Power Structured Light Pattern Generating Laser Coherent s PowerLine structured light laser is a line generator developed for demanding industrial machine vision and scientific applications. Bridging the power gap between the popular Coherent StingRay and Magnum series lasers, this thermo-electrically cooled device is able to emit uniform laser lines at high powers. With exceptional beam pointing and focusing stabilities, the PowerLine laser can be operated in extreme environments ranging from -2 C to +55 C. The laser beam can be modulated by an external signal through a DB-9 connector on the back panel and can operate in either CW or external modulation mode. The laser is protected against over-voltage, reverse polarity of the power supply, over-temperature, and ESD. FEATURES Rugged industrial package Power up to 2W TEC cooled Exceptional pointing stability 445 nm to 88 nm Uniform intensity distribution Focusable Fan angles from 5 to 6 degrees ESD, over-temperature, and reverse polarity protection APPLICATIONS Road/Rail Inspection Tunnel Profiling Infrastructure Lumber Steel/Extrusion Profiling Solar Panel

FOCUSING PERFORMANCE The following figures show the typical focus and depth-of-field performance of the laser. The focus charts indicate the minimum line thickness (at 1/e 2 ) achievable for a specific projection distance. The depth-of-field is defined as twice the distance over which the thickness of the line has increased by a factor of 2.
