10X, NIR Draconis Broadband Beam Expander

Product Details AR Coated for Broadband Tunable Laser Sources Fixed Magnifications Available from 3X to 10X Divergence Adjustable through Non-Rotating Optical Design for Reduced Beam Wander TECHSPEC Draconis Broadband Beam Expanders feature high performance optical designs that have been optimized and tested for broadband use. These beam expanders eliminate the need for critical alignment due to their diffraction-limited performance over large input beam diameters and wide acceptance angles. Their broadband designs enable use with multiple laser lines or tunable lasers, reducing the number of beam expanders required in optical systems. Additionally, the optical design ensures internal focusing of ghost images is not present, which allows compatibility with high power lasers. Mechanical adjustment through a sliding optical design corrects errors in divergence or collimation. TECHSPEC Draconis Broadband Beam Expanders’ C and T input/output mounting threads are compatible with Edmund Optics’ line of threaded mounting components, or mounting can be achieved using an optional mounting clamp. TECHSPEC Draconis Nd:YAG Laser Line Beam Expanders are also available. 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 broadband or ultrafast applications, TECHSPEC Canopus Reflective Beam Expanders are available.
