A device for the spherical orientation of an optical element is provided comprising a support structure, the optical element having an optically useful surface adapted to interact with an incident light beam, a mechanism mounted on support structure and capable of rotating the optical element in space around a first and second rotation axis perpendicular to each other. The mechanism comprises a first rotating assembly around the first rotation axis and a second rotating assembly around the second rotation axis, which first rotating assembly has a through cavity defined around the first rotation axis, the through cavity being adapted to be crossed by the light beam and facing the optical element. The mechanism comprises at least a first electromagnetic actuator arranged to rotate the first rotating assembly and at least a second electromagnetic actuator arranged to rotate the second rotating assembly.

Device for the spherical orientation of an optical element, in particular for directing a light beam, such as a laser beam

A hand-held device is provided for precisely positioning a needle tip at a desired target position into a non-homogeneous material, including a blood vessel. The hand-held device includes a casing hand-held by an operator, a shaft extending along a longitudinal axis and carrying the needle, the shaft mounted in the casing and coupled to the casing to move as a single piece therewith along the longitudinal axis. The hand-held device further includes a sensor unit to provide signals indicative of a physical characteristic of the material wherein the needle tip has to be inserted, and a control unit configured to determine, based on the signals received from the sensor unit, whether the needle tip has reached the target position and to operate a decoupling unit to decouple the shaft and the needle from the casing or to operate an actuating unit to actively move the shaft relative to the casing.
