MultiMode Closed-Loop Scanner
The MultiMode Closed-Loop Scanner brings the accuracy and precision of closed-loop control to the MultiMode. You no longer need to choose between a SPM offering ultra-high resolution imaging and one offering the accuracy and convenience of closed-loop. The modular design of the MultiMode makes it easy to switch between a closed-loop scanner for routine use and an open-loop scanner for ultra-high resolution work. In addition, you will enjoy the same ease of use, reliability, and support that has made MultiMode the performance leader in SPM technology.
Closed-loop control offers a number of benefits for both imaging applications and force measurement applications, as well as enabling precise nanolithography and nano-manipulation. Not only is imaging more accurate, but it is also more convenient because you can zoom and scan exactly where you desire. For force measurements, having closedloop control makes it easy to target specific areas or structures using our “point and shoot” feature or to perform force-volume or nano-indentation arrays over well-defined areas. And of course nanolithography and nano-manipulation really demand the accuracy offered by closed-loop in order to achieve high-quality results.
The MultiMode Closed-Loop Scanner enhances the MultiMode’s excellent reputation for performance, productivity, reliability, and ease of use.
