3X, Ultrafast-Enhanced Silver Canopus Reflective Beam Expander

Product Details HR Coated for UV, Visible, and IR Applications from 250nm to 10μm Multiple Reflective Magnifications from 2X to 5X Monolithic Design for Reduced Thermal Effects and Simplified Alignment Manufactured Using Patented Diamond Turning Technique TECHSPEC Canopus Reflective Beam Expanders are ideal for applications requiring broadband or achromatic beam expansion and a wide variety of light sources. The all-reflective design enables these beam expanders to be used with a variety of lasers including tunable, ultraviolet, and ultrafast sources, while the innovative design ensures high precision with minimal wavefront distortion. A variety of integrated design elements, including reflective flats, threaded holes, and thru-holes, simplify alignment, mounting, and integration into any laser application. The monolithic design ensures performance and stability independent of changes in temperature. TECHSPEC Canopus Reflective Beam Expanders are available in 2X, 3X, and 5X magnifications, along with coating options for the UV, Visible, and IR spectra. For more cost sensitive applications, Edmund Optics also offers TECHSPEC Scorpii Nd:YAG Beam Expanders . For HeNe laser applications, TECHSPEC Arcturus HeNe Beam Expanders are available. For applications where rotating optics are acceptable, the TECHSPEC Vega Laser Line Beam Expanders and TECHSPEC Vega Broadband Beam Expanders are available. For higher precision applications where sliding optics are necessary, please see our TECHSPEC Draconis Nd:YAG Laser Line Beam Expanders or TECHSPEC Draconis Broadband Beam Expanders .
