Vega Broadband Beam Expanders
• AR Coated for Broadband Tunable Laser Sources
• Fixed Magnifications Available from 1,5X 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 Thulium
and Holmium sources.
