Variable Beam Expanders Now Available for 355 nm with 2X - 8X Magnification Range

Aug. 2, 2016

TECHSPEC Variable Beam Expanders offer continuous magnification for high power laser applications where magnification changes may be required, including prototyping or research and development. They are now available in 355-nm wavelength with 2X - 8X magnification range and are particularly suited for UV laser machining. This new model is in-stock and available for immediate delivery for fast turnaround and excellent value.

These UV Beam Expanders feature diffraction limited performance with a guaranteed 1/4? transmitted wavefront. High laser damage threshold anti-reflective (AR) coatings ensure maximum transmittance, while minimizing ghost reflections.
