A JPK Nanowizard 3 AFM is employed in FM-AFM mode and thermal noise mode to measure the frequency shift and the dissipation versus the distance to a glass surface D.. For thermal

The main lens is imaging its object space (right) into its image space (left), distorting it in the process. The world space light field is therefore distorted into an in-camera
