GCO-25 Zoom Beam Expanders


Our Zoom Beam Expanders are designed specifically varying the beam diameter of multimode lasers. Magnification is variable over a range of 2x to 6x or from 5x to 10x by adjusting the knob at the input end. Because of using air-spaced lenses, this sereis can achieve good performance for higher energy laser. An adjustment using the output end focus knob is required to restore beam collimation.
