Abstract
A measuring machine includes a non-contact probe that detects a step gauge without contact. The non-contact probe includes an emitting element that radiates light, a light receiving element that receives the light radiated from the emitting element, and an optical filter that covers an optical path to the light receiving element. The optical filter includes a transmission band in which the light radiated from the emitting element is transmitted and a blocking band in which light to which the light receiving element is sensitive is blocked.
