A method of making a pre-aligned optical mount, including: mounting a desired optical element onto a housing; securing the housing onto a stage having at least four degrees of freedom; aligning the optical element with a specified optical axis by adjustment of the stage; machining the housing to match an optical platform onto which the housing is be mounted; wherein the housing is machined such that an optical axis of the optical element is aligned with a predefined optical axis with respect to the optical platform when the housing is mounted onto the optical platform.

Pre-aligned optical mounts

A braking device including: a piezoelectric element; and a braking portion. The braking portion is configured to be fixed to a member when the piezoelectric element is in a first state, and to be slidable along the member when the piezoelectric element is in a second state. The piezoelectric element changes from one state to another state when a voltage is applied.

Piezoelectric braking device

An imaging incident angle tracking device, including: a light source; a first and second beam splitters or dichroic mirrors; a position sensitive detector; wherein the first and second beam splitters or dichroic mirrors are configured to direct light from the light source to a window surface through an objective lens; the first and second beam splitters or dichroic mirrors is further configured to direct the light reflected from the window surface and through the objective lens into the position sensitive detector. A positioning system, including: a baseplate; a platform; a plurality of strut assemblies connecting the baseplate and the platform; wherein each of the strut assembly includes: a linear actuator; a first flexure assembly and a second flexure assembly at the first and second ends of the strut assembly; the first and second flexure assemblies are rigid along and flexibly bendable orthogonal to the length of the strut assembly.
