         List of Products             Zoom Beam Expanders
 

STS Series Zoom Beam Expanders

  • for collimation of high power lasers

  • variable magnification from 1x up to 8x

  • additional 8 "click into place points“ guarantee best

  • reproduction of magnification

  • high pointing stability < 1 mrad

  • Galilei-design

  • available with and without adjustable divergence

  • UV beam expander made completely from quartz material

  • max. exit pupil depending on the model f30mm or f50mm

Our zoom beam expanders (or called as variable beam expander) are highly corrected 4-lens element systems. The version with divergence adjustment is very user friendly, as the magnification setting and the divergence setting are independent from each other, i.e. the divergence remains unchanged while changing the expansion factor. In addition, the total length of the beam expanders remain constant during zooming and/or divergence setting. For remote controlled setting, we developed motorized versions of our zoom beam expanders. A motor adapter can be incorporated to drive the mechanics used for magnification setting.
