laserfor medical applicationshigh-precision

Overview
The GVM-3113 and GVMW-3113 are galvanometer scanners for precision laser beam steering. GVM-3113 provides a mechanical maximum scan angle of ±20° while GVMW-3113 extends the range to ±40°. Both models weigh 570 g and deliver a repeatability of 8 µrad. These scanners are intended for integration with compatible mirrors and servo drivers.
