    Abstract: A scanning device includes a substrate, which is etched to define a recess in the substrate and to define the following structures contained in the recess: At least first and second mirrors are disposed along a common axis of rotation. Torsion hinges extend collinearly along the axis of rotation and connect the first and second mirrors to the substrate so that the first and second mirrors rotate on the torsion hinges about the axis of rotation. Rigid struts are disposed alongside the axis of rotation and connect the first mirror to the second mirror so that the struts rotate about the axis of rotation together with the first and second mirrors.

    Abstract: Scanning apparatus includes a scanner, which is configured to scan over a field of view falling within a predefined angular range. An interference filter is positioned between the scanner and the field of view and is configured to pass light within a predefined wavelength range that is incident on the interference filter at angles within the predefined angular range, while reflecting the light within the predefined wavelength range that is incident on the interference filter at an angle that is outside the predefined angular range. An ancillary optical element communicates optically with the scanner at a wavelength within the predefined wavelength range via a beam path that reflects from the interference filter at the angle that is outside the predefined angular range.
