Edmund Optics Techspec Variable Beam Expanders

Edmund Optics Techspec Variable Beam Expanders offer continuous magnification for high-power laser applications where magnification changes may be required, including prototyping or research and development.

The product provides 1-3X and 2-8X continuous magnification. Design features include a 1/4λ transmitted wavefront, while its high laser damage threshold anti-reflective (AR) coatings ensure maximum transmittance while minimising ghost reflections.

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

The product is 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.
