Closed Loop Scanner Upgrade

Bruker offers the option of adding a Closed Loop Scanner to the Hysitron TI 950 TriboIndenter. The closed loop scanner provides an increased scan range (X-Y: 100μm, Z: 15μm) with extremely low scanner bow and a scanning linearity of greater than 99.95%.

The closed loop scanner offers real-time position feedback and only takes milliseconds to settle. It also eliminates piezo creep and hysteresis by utilizing capacitive sensors for real-time position feedback and sub-nanometer noise performance.

The Closed Loop Scanner option is ideally suited for difficult applications by providing the ability to move in increments as small as a fraction of a nanometer with high precision and speed.

The ultra-fast settle time and quick positioning response of the Closed Loop Scanner allows researchers to run piezo automation experiments 2× to 3× faster than while operating in open loop mode. Additionally, the absence of piezo drift simplifies the process of identifying and targeting small surface features. The Closed Loop Scanner provides the capability of accurately positioning the probe on the desired surface feature the first time, every time.
