Product Family Description

  • λ/10 Transmitted Wavefront
  • Sliding Optics Collimation Adjustment Minimizes Beam Wander
  • Compact Galilean Designs 
  • Broadband Design to Accommodate Multiple Laser Wavelengths or Tunable Lasers

TECHSPEC® UDA (Ultra Divergence Adjustable) Fixed Broadband Beam Expanders feature high performance optical designs that have been optimized and tested for broadband use. These beam expanders eliminate the need for critical alignment due to their diffraction-limited performance over large input beam diameters and wide acceptance angles. Their broadband designs enable use with multiple laser lines or tunable lasers, reducing the number of beam expanders required for your optical system. Additionally, the optical design ensures internal focusing of ghost images is not present, which allows compatibility with high power lasers. Focus adjustment is also provided, which can be used for divergence correction or collimation. TECHSPEC UDA Fixed Broadband Beam Expanders C and T input/output mounting threads are compatible with Edmund Optics’ line of threaded mounting components, or mounting can be achieved using an optional mounting clamp.

Note: Contact our Sales Department for custom wavelength or magnification requests.
