Abstract
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.
