Zoom Beam Expander

Zoom Beam Expander
  • Adjustable expansion ratio
  • Adjustable divergence
  • Galilean design
EKSMA OPTICS offers compact Galilean type zoom beam expanders for Nd:YAG lasers fundamental and its harmonics wavelength: 1064 nm, 532 nm and 355 nm.  Zoom beam expander provides variable expansion ratio of 2x-8x, 1x-8x, 1x-3x with adjustable focus to correct for laser beam divergence.
