Vega™ Broadband Beam Expanders

• AR Coated for Broadband Tunable Laser Sources
• Fixed Magnifications Available from 2X to 20X
• Divergence Adjustable through Rotating Optical Design

TECHSPEC^® Vega™ Broadband Beam Expanders are designed for demanding tunable laser sources. These compact beam expanders are optimized at a wide range of wavelengths, with designs achieving λ/10 transmitted wavefront error and no internally focusing ghost images for compatibility with high power lasers. TECHSPEC Vega Broadband Beam Expanders are easily integrated into prototype and advanced applications while maintaining quality across the adjustment range. They are ideal for medical laser applications employing highly tunable Thulium and Holmium sources.

Note: This product family was previously known as TECHSPEC DA Fixed Broadband Beam Expanders.

TECHSPEC Vega™ 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 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. For broadband or ultrafast applications, TECHSPEC Canopus™ Reflective Beam Expanders are available.
