PSIA XE-100 Scanning Probe Microscope “ours is not just an AFM”  AFM3.JPG

The new XE series SPM was developed to have the following advantages: 1) Scan accuracy: There is no cross talk between the x-y and z axes, and one can achieve high scan accuracy. 2) Sample size: Since the sample is scanned by a flexure scanner only in the x-y direction, large samples as well as small samples can be scanned at sufficiently high speed. 3) Scan speed: Since the z scanner has a high resonance frequency with high force, the z servo frequency response is much greater than in conventional AFM. 4) Convenience: Since the laser beam aligning mechanism is fixed to the head, it is possible to produce alignment fixtures of adequate size for convenient and precise adjustment without requiring any tools. 5) Optical vision: Since there is enough clearance above the cantilever, it is possible to accommodate a direct on-axis optical microscope.
