Abstract: Systems and methods for imaging a surface, including a nano-positioning device including a cantilever with an optically transparent microsphere lens coupled to the distal end of the cantilever. An optical component can focusing light on at least a portion of the surface through the microsphere lens, and focus light, if any, reflected from the surface through the microsphere lens. A control unit communicatively coupled with the nano-positioning device can be configured to position the microsphere lens at a predetermined distance above the surface.
