Variable Laser Beam Expander provides continuous magnification.

Press Release Summary:

Available in 1X–3X or 2X–8X magnification ranges for 532 or 1,064 nm or broadband visible wavelengths, TECHSPEC® Variable Beam Expanders offer continuous magnification for laser applications where magnification changes may be required. Galilean designs feature 1/4 λ transmitted wavefront, and AR coatings ensure maximum transmittance while minimizing ghost reflections. Non-rotating internal translation and focusing mechanisms continuously adjust magnification and laser divergence.

TECHSPEC Variable Beam Expanders Provide Continuous Magnification

Adjustments do not affect overall housing length

Barrington, N.J. - Edmund Optics® (EO), the premier provider of optical components, will unveil their new TECHSPEC® Variable Beam Expanders at the CLEO show in San Jose, CA. These versatile beam expanders offer continuous magnification for high power laser applications where magnification changes may be required, including prototyping or research and development.

Edmund Optics' TECHSPEC Variable Beam Expanders provide 1-3X and 2-8X continuous magnification. These Galilean designs feature a guaranteed 1/4λ transmitted wavefront. High laser damage threshold anti-reflective (AR) coatings ensure maximum transmittance, while minimizing ghost reflections.

Non-Rotating Optics Design

TECHSPEC Variable Beam Expanders use non-rotating internal translation and focusing mechanisms to continuously adjust magnification and laser divergence without any effect on the overall housing length. The compact design eliminates the need to make system accommodations for changes in length and simplifies system integration. It easily adjusts for laser beam divergence.

Continuous Magnifications of 1-3X and 2-8X are available

TECHSPEC Variable Beam Expanders are available in two different magnification ranges - from 1-3X or 2-8X - for 532 nm, 1064 nm, or broadband visible wavelengths. Custom fixed magnification requirements can also be accommodated.
