Abstract: The present invention relates to transducer housing and a tool for opening and closing the transducer housing (20). The transducer housing comprises a base body (22) and a lid (24) which are releasable coupled with a rotational coupling (26). The lid (24) comprises a contact area (42) formed to be engaged by a driving pin (64) of the tool (10) in order to open or close the transducer housing (20) upon a rotation of the lid (24) relative to the base body (22). The tool (10) comprises a base portion (12) and an upper portion (14) that are coupleable wherein the upper portion can be rotated relative to the base portion.

Abstract: A measuring setup for measuring an optical device under test—DUT—includes an optical signal source for applying an optical signal to the DUT, and an optical receiver unit for measuring a response of the DUT on the applied signal. A measurement unit is coupled between the optical signal source and the optical receiver unit. The measurement unit comprises an optical circuit to provide optical signals from and/or to the DUT for measuring the DUT, whereby the optical circuit comprises optical components showing high susceptibility to mechanical noise. A shielding unit receives the optical circuit and provides at least partial shielding of the optical circuit and/or the DUT against mechanical noise.
