Lighting system for multi-probe microscope and operating method therefor

Abstract

A probe microscope comprises a probe array with an array of probes, each probe comprising a cantilever and a probe tip. A lighting system comprises a plurality of light sources. Each light source is configured to output a respective light beam. A lens array comprises an array of lenses. Each source lens is positioned to receive a respective one of the light beams from the lighting system. An objective lens is configured to receive the light beams and focus each light beam onto the cantilever of a respective one of the probes. The lighting system is configured to modulate a power of the light beams to actuate the probes, and the lighting system is configured to modulate the power of some or all of the light beams independently.
