Title: Heinz Lehr: Innovator in Optical and Motor Technologies
Introduction
Heinz Lehr is a notable inventor based in Berlin, Germany, recognized for his contributions to optical and motor technologies. With a total of five patents to his name, Lehr has made significant advancements in the fields of dental imaging and linear motor systems.
Latest Patents
One of his latest inventions is a dental intra-oral camera. This innovative device features an imaging system designed to depict objects located in front of the camera's observation window on a recording unit. The imaging system includes at least one focusing unit for setting an appropriate focus and an aperture unit that allows for the formation of a variable aperture. Notably, the aperture setting operates independently of the focus adjusted by the focusing unit.
Another significant patent is the gliding field linear motor. This invention pertains to a three-phase linear synchronous motor that includes an armature with an axial bore through the center, allowing for the installation of an optical element, such as an optical lens. The armature is equipped with a sliding sleeve that houses an axially polarized permanent magnet with an unobstructed center bore. The armature is guided within a stationary outer sheath, and its displacement is achieved through the interaction between the permanent magnet and a moving magnetic field along the optical axis. This system is particularly suitable for the miniaturization of optical systems.
