Model: MF-4456
The focus assist option replaces the manual optical microscope support on the TT-AFM. This option includes video optics, control electronics and control software. Installing the focus assist mechanical assembly is simple, requiring only a few socket head screws/replacements.
Included with the focus assist is the same optic offered on the TT-AFM. The optic has a 7:1 mechanical optical zoom and gives a resolution of
Features and Benefits of Focus Assist
- Accurate focus control
- Facilitates rapid probe approach
- Follow probe when making tip approach
- Control focus while AFM is in acoustic box
Software
Software for Focus Assist is integrated with the AFMControl software used on the TT-2 AFM. Using the software is easy. Simply focus the optical microscope on the probe, and then on the sample. Once this registration is completed, you can use the software to move directly to the sample, to the probe, or you can even have the optic follow the probe during probe approach.
With Focus Assist it is possible to rapidly zoom into a speciffic area of a sample with extreme accuracy, facilitating highly successful scanning.
