Abstract:
A scanning probe microscope capable of radiating light on a sample without moving the sample from the scanning probe microscope and measuring the sample with controlling the condition under which the sample is placed and without changing the location of the sample is provided. The scanning probe microscope includes a cantilever having a probe on a top end thereof, sample moving means for moving the sample, detachable cantilever bending amount detecting means for detecting bending amount of the cantilever by means of a laser beam and exposure means for exposing the sample to light from upper side of the cantilever, wherein the cantilever bending amount detecting means is independently detachable when exposure of the sample is carried out.
