More Information
Summary:Optical component (10a) for a device for emitting a first beam cluster (4) and for receiving at least one second beam cluster (5) comprises a one-part element (1, 2) made of glass, quartz or another inorganic optical material with a first segment (6) refracting the first beam cluster and at least one second segment (7) refracting the second beam cluster. The first segment is surrounded by the second segment. A hollow (8a) is provided which surrounds the first segment and is designed so that, within the device, optical disturbances of scattered beams (9) of the first beam cluster with the second beam cluster are directly or indirectly prevented. Independent claims are also included for: (1) Device for distance measurement comprising the above optical component and a receiving beam cluster arranged coaxially to an emitting beam cluster; (2) Measuring instrument comprising the above distance-measuring device; (3) Alternative optical components; and (4) Processes for producing an optical component.
