dynAXIS 421 Compact High Performance Galvanometer Scanner

SCANLAB expands its product range with the dynAXIS 421 galvanometer scanner. This moving-magnet closed-loop galvo is particularly suitable for applications with small apertures and highest dynamic performance. With its very small dimensions, it is ideal for compact and handheld devices, including medical and ophthalmic instruments. The dynAXIS 421 is available with both analog and digital servodriver boards, and a variety of mirrors and coating options. Quality Made in Germany Key Features • Suitable for very small apertures (3 mm – 7 mm) • Optimized motor design enabling faster and more efficient...

Examples of suitable SCANLAB servo boards Recommended Servo-Driver Boards In combination with the new, compact SCANLAB microISB digital servo-driver board, the dynAXIS 421 achieves maximum dynamic performance and precision with low heat generation. The digital technology also provides the system status values and output signals relevant for the respective application. Very high accelerations and scan rates can also be achieved with the high performance and compact miniSSV analog servo-driver board. Also the miniSSV allows optimized scan efficiency while heat generation is kept low. microISB (digital...
