    Abstract: Spectral beam combining systems including a multi-element transform optic. In certain examples the multi-element transform optic includes a first cylindrical optical element having positive optical power in a first axis, a second optical element having negative optical power in the first axis, and a third toroidal optical element having positive optical power in the first axis and either positive or negative optical power in a second axis that is orthogonal to the first axis. The first and third optical elements are positioned on opposite sides of the second optical element and equidistant from the second optical element. The multi-element transform optic has an optical path length extending between a front focal plane and a back focal plane that is shorter than an effective focal length of the multi-element transform optic.

    Abstract: An on-gimbal telescope pointing assembly can comprise a head mirror operable to rotate to adjust an elevation angle of the pointing assembly and an all-reflective telescope operable to rotate to adjust an azimuth angle of the pointing assembly. The all-reflective telescope can comprise a fold mirror defining an output coude path of the all-reflective telescope. The pointing assembly can be operable to rotate about the coude path such that receiving optics can remain fixed while the pointing assembly rotates.

    Abstract: A thermal-mechanical linear actuator can include a first stage comprising one of a positive coefficient of thermal expansion (“CTE”) material or a negative CTE material and a second stage comprising the other of the positive CTE material or the negative CTE material. The second stage can be at least partially inserted into the first stage. The actuator can further comprise a thermal isolator disposed between the first stage and the second stage to thermally isolate the first stage from the second stage. Heat inputs can be provided where the heat inputs can control the temperature of the first and second stages independently. A hyperbolic meta material can be wrapped or coated around the first stage.

    Abstract: An imaging telescope including a first mirror configured to receive electromagnetic radiation having a first polarization state and to reflect electromagnetic radiation having a second polarization state, the first mirror including a multi-layer dielectric (MLD) coating configured to convert the first polarization state to the second polarization state, and a plurality of reflecting configured to receive the electromagnetic radiation having the second polarization state reflected from the first mirror and to reflect and focus the electromagnetic radiation having the second polarization state onto an image plane of the imaging telescope.
