FEATURES
1. Light aluminum-frame design and demountable structure make carrying and teaching easy and convenient.
2. Scan head and sample stage (XY table) are designed together with strong stable performance.
3. Precision laser detection and probe alignment device make the laser-adjustment and probe-replacement simple and easy
4. Smart auto-approaching method: the step-motor moves the sample vertically close to the probe, avoiding accidental cantilever crashes. 
5. Adjusting servomotor to move the sample approaching tip manually or automatically in order to carry out precision positioning of the scanning area as well as to avoid an accidental cantilever crash
6. The coarse sample-to-tip approaching may be made manually or automatically.; in order to carry out precision positioning of the scanning area as well as to avoid an accidental cantilever crash
7. Camera with 4X magnification allows cantilever checking and sample positioning: the image is always focussed on the cantilever  and therefore allows an easy observation of the sample surface
8. Springs suspension warrants good performance for vibration isolation 
9.  Integrated scanner nonlinearity correction makes the measurement precise within 98%.
