An apparatus includes a device mount configured to be coupled to a component. The apparatus also includes an inner hub coupled to the device mount by a first flexure, where the first flexure is configured to permit translational movement of the device mount within the inner hub along a first axis. The apparatus further includes an outer hub coupled to the inner hub by a second flexure, where the second flexure is configured to permit translational movement of the device mount and the inner hub within the outer hub along a second axis different from the first axis. The first and second flexures form a compound nested flexure. The outer hub is configured to be coupled to a support structure and to permit both (i) translational movement of the apparatus along a third axis different from the first and second axes and (ii) tip/tilt adjustment of the apparatus.
