Beetle UHV VT AFM/SEM
Beetle UHV VT AFM/SEM Overview
How Do You Bridge the Gap Between Resolution and Field of View?
A 100 nm particle sounds vast in our nano-research world. But searching for a feature even that size on a 10-20 mm2 SPM sample can be futile. It is far too small for optical imaging to assist navigation, and scanning with an SPM can waste valuable research time. How do you bridge the gap between optical and SPM techniques to assure productive results? RHK Provides the Solution: Meet the UHV Probe Positioning System. Swift SEM-guided probe placement in a wide field of view, integrated with uncompromised AFM/STM resolution.
