General Optics
Beam Expanders
Transform the diameter of high-power CO2 laser beams with these Galilean telescopes (no internal focus) beam expanders, suitable for a wide range of applications.
These beam-expanding telescopes utilize precision ZnSe optics to offer low insertion loss and high-power operation, and are available with several different input beam diameter and magnification combinations.
