Abstract
The purpose of the present disclosure is to provide a defect inspection device with which it is possible to suppress variation in an output signal occurring when an imaging operation condition for an image sensor is changed. The defect inspection device according to the present disclosure comprises a detector that outputs a detection signal for signal light generated by irradiating a sample with light. The detector is controlled so that a first operation state of the detector in a first signal acquisition condition and a second operation state of the detector in a second signal acquisition condition are the same.
