PinPoint mode is an imaging method in AFM that differs from contact and non-contact modes. While contact and non-contact modes rasterize horizontally the sample to measure its features, PinPoint mode operates by vertically approaching and retracting the AFM probe at each designated points. This method captures detailed surface information of the sample, measuring topographical features and obtaining various nanomechanical information.
