Designed for use with CO2 Lasers, these Adjustable Beam Expanders offer precise collimation of output beams in a compact, Galilean design. By adjusting the distance between the two ZnSe lenses via the focus ring, the user is able to compensate for slightly convergent or divergent entrance beams. All CO2 Adjustable Laser Beam Expanders have antireflective coatings on every lens surface. AR coating transmits >99% of optimum wavelength (10.6μm).
