Abstract:
An optical system comprises a detector to determine one or more intensities of light impinging on one or more locations of the detector and an optical element to direct light towards the detector along a detection axis. The detector and optical element are coupled together by three or more substantially flat flexures respectively defining three or more flexure planes parallel to the detection axis. The three or more substantially flat flexures maintain an alignment of the optical element to the detector with changes in temperature.

Abstract:
An actuator includes an inner element coupled to an outer element by a linear-motion bearing that provides a single degree of translational movement of the inner element with respect to the outer element along a longitudinal axis. The inner element includes a permanent magnet and the outer element includes a conductive winding with a first coil wound in first direction around a first pole of the permanent magnet and a second coil wound in a second direction around a second pole of the permanent magnet.
Abstract:
A scanner for scanning a dental site comprises a base, a detector mounted to the base, and an optical element to redirect light reflected off of the dental site towards the detector along a detection axis in a first direction. Two or more flexures couple the optical element to the base, wherein the two or more flexures maintain an alignment of the optical element to the detector with changes in temperature.

Abstract:
A scanner includes a lens assembly comprising a lens having a lens axis and a positioning system to adjust a focal plane of the lens assembly. The positioning system includes an outer element, an inner element that houses the lens assembly, and a linear-motion bearing that couples the inner element to the outer element. The linear-motion bearing includes a first element coupling and a second element coupling. The linear-motion bearing provides a single degree of translational movement of the inner element along the lens axis.
