Motorized Beam Expander

Motorized Beam Expander (MBE) is a precision beam expander designed for automated applications. The device allows rapid and independent divergence as well as magnification adjustment during its operation. MBE features high pointing stability as well as expansion accuracy.

Moreover, high expansion repeatability and longevity of the product helps to increase the efficiency of the application as frequent calibration and replacement can be avoided. In addition, MBE optical design enables it to be used in high-power laser applications as there are no internal foci.


  • High pointing stability: <100 µrad
  • High expansion repeatability: ±0.6%
  • Long service life: >3.6 million cycles
  • Suitable for high-power applications
