China Laser Beam Expander – Fixed Expansion
Fiber, CO2, UV, Green Laser Beam Expander from 1X-50X, 355nm, 532nm, 1064nm,10.6um, 9.4um
Most laser beam expanding mirrors are of Galilean design and consist of a combination of positive and negative lenses. They are widely used due to their low expansion coefficient and simple, compact construction. Smaller focused spots are achieved by amplifying the laser beam.
