    Abstract: Optical assembly containing a) at least two pairs of dichroic beamsplitting elements grouped together such that first sides of these elements are parallel and immediately adjacent to one another and to a predetermined line, and b) two optical lenses disposed such that light transmitted through the lenses towards the beamsplitting element passes through the elements without being scattered at the first sides. Optionally, a first dichroic beamsplitting element in a first pair and a first dichroic element in a second pair have equal optical properties. Imaging probe—for example, a laparoscope—employing such optical assembly.

    Abstract: An actuator assembly (16) for moving a device (22) includes a stator component (30), a mover component (32), a measurement system (18), and a signal processor (20). The measurement system (18) includes (i) a magnet assembly (244) that is coupled to and moves with the mover component (32); and (ii) a plurality of spaced apart sensors (246A). The magnet assembly (244) produces a magnetic field (244B) that moves relative to the stator component (30) as the mover component (32) moves along a mover axis (32C). Each sensor (246A) is a transducer that generates a sensor signal that varies its output voltage in response to the changing magnetic field (244B) from the magnet assembly (244) as the mover component (32) is moved relative to the sensors (246A). The signal processor (20) receives the sensor signals and estimates a position of the mover component (32) along the mover axis (32C) based at least in part on the sensor signals.

    Abstract: A stage assembly that moves a device includes a stage that retains the device, a stage mover that moves the stage, a measurement system that provides a measurement signal that relates to the position or movement of the stage, and a control system that control the stage mover. The control system can use an estimator to estimate the position of the stage in the event the measurement signal is lost. Alternatively, the control system can be used to urge the stage against a base assembly when the measurement signal is lost to inhibit the movement of the stage.
