Laser Optics, Heads and Beam Delivery Components

Laser optics, heads and beam delivery components are used in laser cutting machines, laser welding and marking systems. Many types of products are available. Examples include beam benders or mirror blocks, beam collimators, beam expanders, beam pipes or tubes, beam shutters or dumps, beam splitters, beam switchers or galvo mirrors, circular polarizers or phase retarders, fiber optics and cable beam guides, galvanometer scanners, gas assists or laser nozzles, guidance modules or flying optics, laser heads or focusing units, pointing diodes or beam injectors, reflection isolators, resonator optics, and scan lenses. Lens focusing optics, reflective focusing optics and monitoring sensors and systems are also available. With lens focusing optics, the appropriate lens must be selected based on the wavelength and power of the laser beam. Typically, lens focusing optics requires water-cooling during operation. Reflective focusing optics or mirrors are used on very high power laser systems where a lens focusing system would absorb too much of the laser power and overheat. Monitoring sensors or systems detect conditions and provide feedback or control during processing.
