摘要: A vario-astigmatic beam expander (200) is capable of collimating an astigmatic light beam, or inducing astigmatism in a well-collimated by passing the through combination spherical (202) and cylindrical (206, 208) lenses, whereby both degree axis induced are continuously adjustable. The has applications industrial laser processing systems.
