Our zoom beam expanders (or called as variable beam expander) are highly corrected 4-lens element systems with variable magnification from 1x up to 8x and Galilei-design.

Product Introduction

STS Series Zoom Beam Expanders

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.
