專業Zoom Beam Expanders (Adjustable)廠商

In order to vary the magnification of the beamexpander while still keeping the focus at infinity, two lens elements have to be moved. In the C-ZBE these movements are not actuated by a single adjustment ring, but have been kept separate as 2 adjustment rings, labelled X and Y.
