  • Measuring head of an endoscopic device and process for inspecting and measuring an object
    Patent number: 10165935
    Abstract: A measuring head of an endoscopic device is provided. The measuring head has an optical projection unit (projection optics) intended and designed to illuminate an object to be examined with light, and an optical measurement unit (measurement optics) intended and designed to record the light reflected or diffused from the object to be examined. It is provided that the optical measurement unit (measurement optics) has an aperture diaphragm of which the aperture is settable.
