摘要:
The invention relates to an optical probe (1) for optically testing objects to be measured, said probe comprising: a fixed probe part, and a probe part (5) that can be rotated about a rotational axis (3) and is mechanically and optically coupled to the fixed probe part, the rotatable probe part (5) comprising at least two optical outputs (10a; 10b; 10c) for releasing measuring beams. The measuring beams project perpendicularly in relation to the rotational axis (3), from the optical outputs, each with different focus distances d (15). The invention also relates to a device for the interferometric measurement of measuring objects, an interferometer being connected to the optical probe (1) in the device.
摘要:
The present invention relates to a coupling unit for transferring a medium from a stationary component to a rotating component, comprising a first stationary ring (7) attached to a stationary part (3), a second rotary ring (8) attached to a rotary part (4) and rotating together with the rotary part (4), a bearing (9) disposed between the first ring (7) and the second ring (8), a ring gap (10) disposed between the first ring (7) and the second ring (8), an inlet line (11) disposed on the first ring (7) for feeding the medium, an outlet line (12) disposed on the second ring (8) for transporting the medium, wherein the outlet line (12) rotates with the second ring (8), an inner sealing element (13) sealing the ring gap (10) on a radially inner side, and an outer sealing element (14) sealing the ring gap (10) on a radially outer side.
