Polygonal Scanners

Lincoln Laser Co.Request Info
 
Lincoln Laser Co.’s KW Series polygonal laser scanners feature copper mirrors for materials processing applications using high-energy laser sources. When galvanometer mirrors are enlarged to compensate for high-power lasers, the scan rate slows down. The polygonal scanners dissipate heat more efficiently and produce faster scan rates because the copper substrate acts as a large heat sink that draws heat away from the mirror facets. Additional heat dissipation occurs as the polygonal mirror rotates, allowing the laser beam to transfer rapidly from facet to facet and minimizing dwell time on any single facet. The scanners accommodate beam power densities of 1000 W/mm2 and produce scan angles of >120° and scan rates of >10 kHz. They can be custom designed to meet thermal, optical, speed and accuracy requirements for lasers of all wavelengths and power levels.

GLOSSARY
galvanometer mirror
A small mirror, sometimes plane and sometimes concave, attached to the rotating coil of a galvanometer to cause a spot of light to move along a scale.
heat sink
A series of flanges or other conducting surfaces, usually metal, attached to an electronic device to transmit and dissipate heat that might damage internal circuitry.
optical
Pertaining to optics and the phenomena of light.
scanner
1. A device used to trace out an object and build up an image. One of the most common of these types is video scanning. The scanning takes place inside the television tube as electrons, guided by electron optics, sweep linearly across a tube face coated on the inside with a phosphorescent material. A scanner can convert a paper drawing or photograph into pixels on a display screen. Scanners are also used to relay information in optical data processing. 2. A device that automatically measures or...
