  • Designed for high power laser applications:
    • IBS-coated UV FS thin lenses
    • High total transmission: >99%
    • Low GDD: relative pulse broadening <20%
  • AR-coated for: 1030/1064 nm, 515/532 nm, 343/355 nm
  • Fixed magnifications from 1.5X to 10X
  • Divergence adjustment: non-rotating optics, sliding lens design

EKSMA Optics offers Galilean type beam expanders with thin UV FS lenses suitable for femtosecond applications. Fixed Ratio Beam Expanders are designed to increase the diameter of a collimated input high power laser beam to a larger collimated output beam. Fixed Ratio Beam Expanders can be adjusted for the input beam divergence angle to obtain collimated, divergent or focused beam at the output. They feature non-rotating divergence adjustment by sliding lens design.
