LINOS Manual Variable Magnification Beam Expander

The LINOS^® Manual Variable Beam Expanders are specially designed for optical beam forming in laser material processing. Offering continuous variations of the laser beam diameter and divergence, these manual variable beam expanders help optimize focus diameter, focus position and beam propagation within a laser system. The LINOS Variable Beam Expander features precise mechanical scales that allow users to adjust the settings for highest reliability and repeatability. With superb pointing stability, these beam expanders guarantee excellent imaging quality over the full expansion range.
