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.
The LINOS low outgassing UV Beam Expander 1x-4x is the first of its kind featuring stainless steel design in an off-the-shelf UV standard product to minimize potential contamination and extend product lifetime for optimal diffraction limited performance. This product offers higher durability to enable higher UV pulse energies and shorter laser pulses that are essential for laser material processing applications in the semiconductor, wafer processing and electronic display industries.
