General purpose probes are designed for routine AFM measurements. Lateral resolution down to 5 nm is attainable for scan size below 1 μm when using the probes.

Probes
GP probe is a single-crystal Silicon probe with tertahedral tip. The tip is inclined and located at the very end of the cantilever for easier positioning into the area of interest using video camera.
NSC/CSC probe tips have conical shape. There is a wide range of available cantilever shapes and special coatings for tip and cantilever backside.
Typical tip radius 10 nm
Tip aspect ratio more than 3:1(typical 4:1)
Tip height 15±2.5 μm
Probe material p-type Silicon (Boron doped)
Tip inclination angle 19.5°
Typical tip radius 10 nm
Tip cone angle 40°
Tip height 20..25 μm
Probe material n-type Silicon (Phosphorous doped)
general purpose
Lateral resolution down to 5 nm for scan size below 1 μm.
