Teaching/Basic STM
Teaching/Basic STM
Main feature:
1. Easily and quickly obtain nanometer surface features
2. Intuitive operation and quick start
3. The most economical and best nano measurement tool

Provide three-dimensional surface morphology images, including surface roughness, particle size, height difference and spacing

Brand: FSM
Model: FM-STM

Want to find a nano measurement device that can be used for research and teaching within a limited budget,
It can be so simple!
The most efficient and affordable STM provides a brand new choice for physics education and basic nano research!
It will also set off a huge wave of popularization of nano measurement!

1. Miniaturized and detachable design --- the use of space is flexible, easy to carry and classroom teaching
2. The probe base and the sample stage (scanner) are integrated into one body-the scanning stability is higher
3. The single axis drives the sample to automatically approach the probe vertically-accurately positioning the scanning area so that the needle tip is perpendicular to the sample scan
4. Motor controlled pressurized electric ceramic automatic needle down mode --- protect probe and sample
5. Side CCD observation system --- Instantly observe the state of the needle under the probe and locate the sample scanning area
6. Spring suspension anti-vibration system --- simple and practical, desktop space saving and excellent effect
