TECHSPEC® Vega™ Laser Line Beam Expanders are designed for demanding laser applications including laser materials processing, medical, and research. These compact beam expanders are optimized at common laser wavelengths, including Nd:YAG wavelengths, for high performance transmitted wavefront, with designs achieving λ/10 transmitted wavefront error. To ensure compatibility with high power lasers, these beam expanders are designed to prevent ghost images from focusing on internal surfaces. TECHSPEC Vega Laser Line Beam Expanders easily mount with M30 x 1 threading and provide excellent value both for single unit purchases as well as volume integration.
Note: The length of these beam expanders will change upon divergence adjustment, typically by 1 to 2mm from the specified length.
TECHSPEC® Vega™ Broadband 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.
