Which is a good atomic force microscope
The laser detection head and sample scanning table are integrated into one, stable and reliable;
Precision laser and probe positioning device, easy and convenient to replace probes and adjust light spots;
◆ Single axis drive sample automatically approaches the probe vertically, accurately locates the scanning area, and makes the needle tip perpendicular to the sample during scanning;
Intelligent needle insertion method for motor controlled pressurized ceramic automatic detection, protecting probes and samples;
4X objective lens optical positioning, no need for focusing, real-time observation and positioning of probe sample scanning area;
Spring suspension type shock absorption method, simple and practical, with good shock absorption effect;
◆ Metal shielded soundproof box,
