VarioSCAN 20i

Share this on social media:

Scanlab has released the varioScan 20i, a digital control for smart focusing. The device builds on the successful intelliScan series of digitally controlled scan heads by delivering improved Z-axis performance for applications requiring highly dynamic and precise positioning within a 3D processing volume. The varioScan 20i delivers twice the Z-focus shift than previously available on a standard varioScan.

The varioScan 20i's digital encoder feedback and control system offers the advantage of improved dynamics, elimination of drift effects, and a wide variety of operational data returned to the RTC PC Interface board via a separate status channel. Users now have the possibility of monitoring the actual position values of the varioScan 20i during the entire run time of an application, as well as querying data from a comprehensive suite of operational parameters available via the varioScan 20i's separate status channel.
