Abstract
An atomic force microscope equipped with an optical measurement device is disclosed. An atomic force microscope equipped with an optical measurement device which acquires characteristics of a surface of a measurement target by moving a probe along the surface of the measurement target while scanning the measurement target on an XY plane using an XY scanner for supporting the measurement target, includes: an optical measurement device including a lighting unit configured to allow light to enter the surface of the measurement target, and a detection unit configured to detect light reflected by the surface of the measurement target, the optical measurement device being configured to acquire the characteristics of the surface of the measurement target by the scanning by the XY scanner; and a control device configured to control an operation of the atomic force microscope and an operation of the optical measurement device.
