Compact motorized laser beam expanders MEX

 Michael ILUZ

Main features: 

  • Highest beam pointing stability (< 0,1 mrad)
  • All-in-one design with integrated controller
  • Two lenses simultaneous movement assuring no misfocus
  • Absolute encoder (both lenses)
  • Adjustment time <1s (all magnifications)
  • Fused silica optical elements
  • No homing after switching on/off
  • Diffraction limited performance for all magnifications

Application examples: 

  • Precise laser micromachining
  • Life sciences
  • Research



Motorized laser beam expanders MEX series are used to increase the laser beam diameter and adjust divergence. Standard or custom-made beam expanders feature a unique mechanical closed-loop sliding-lens design ensuring high pointing stability and minimal dimensions.

These variable magnification (zoom) beam expanders and reducers are designed for the required wavelength and each type of our beam expanders has motorized divergence adjustability.
