Laser optical components are very common parts of laser machines. Laser comes from laser generator and gets focused after going through a series of mirrors/ lens/ windows, like Galvo scanner mirror, F-theta lens, protective window, focus lens, collimator lens, beam combiners, beam expanders, etc. For different laser applications (marking, welding, cutting, etc.), we use different optical parts because of the different wavelength of the laser beam itself. The wavelength of fiber, YAG and DP laser is 1064nm; wavelength of CO2 laser is 10.6um; wavelength of UV laser is 355nm; wavelength of green laser is 532nm. Suntec Laser is always dedicating to provide various optical parts for different laser systems.
