4X, Coherent CO 2 Beam Expander

Product Details Designed for CO 2 Laser Sources at 10.6μm Compact Housing for Easy System Integration Coherent Infrared ZnSe Optical Elements Coherent CO 2 Beam Expanders are designed to collimate and improve the energy distribution of high power CO 2 laser beams. Featuring premier grade Zinc Selenide (ZnSe) optical elements from Coherent, these beam expanders provide minimum beam deviation and greater than 99.4% transmission at 10.6μm. A high-efficiency anti-reflective coating on the ZnSe substrates results in reflectance less than 0.2% per surface and absorbance less than 0.1% per surface at 10.6μm. Coherent CO 2 Beam Expanders feature a compact housing design with M25 input threading for easy integration into CO 2 laser systems. For additional expansion power options, please contact us .
