Building on SCANLAB's highly successful 
intelliSCAN® series of digitally controlled scan heads, the varioSCANde®20i
delivers unprecedented Z axis performance for applications requiring
highly dynamic and precise positioning within a 3D processing volume.
The varioSCANde®20i delivers twice the Z focus shift than previously available on a standard varioSCAN.
The varioSCANde®20i's true 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 varioSCANde®20i during the entire run time of an application as well as querying data from a comprehensive suite of operational parameters available via the varioSCANde®20i's separate status channel.
SCANLAB's innovative iDRIVE® technology continuously raises the standard of high performance laser beam positioning in 3 axes.
