The inspection/measurement device includes: an irradiation section that irradiates a laser beam to a surface of a specimen; and a detection section that detects scattered light from the surface of the specimen and generates a detection signal. The detection section includes: a photon counting sensor that outputs M output signals from photo-detecting elements of N pixels (M and N are natural numbers, and M<N); M current-voltage conversion sections that execute current-voltage conversion on the output signals of the photon counting sensor respectively; a voltage application section that applies reference voltages to the current-voltage conversion sections; and a detection signal generation section that generates a detection signal on the basis of the outputs of the current-voltage conversion sections."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inspection device and measurement device","description":"A detection circuit for accurately detecting a very small foreign material and an inspection/measurement device using the same are provided.
