An optical system is provided. The optical system includes a corrector lens that is configured to reduce aberrations in electromagnetic radiation (EMR) received from a window having a window axis of symmetry. A rotation mechanism is coupled to the corrector lens, and is configured to selectively rotate the corrector lens about an optical axis of the corrector lens to maintain a Y-axis of the corrector lens in a same plane as the window axis of symmetry of the window.

Method for correcting optical aberrations in electromagnetic radiation in an optical system

A magnetic levitation system comprising a control system configured to control six degrees of freedom of a levitated object, wherein each degree of freedom has at least a third order roll off. Another system and a method are also disclosed.

The present invention comprises a three-axis damping system employing dampers and springs in spatially oriented arrays to isolate an object against translational forces in any direction as well as rotational forces. The inventive system also is biased in the vertical static position to compensate for gravity.
