ABSTRACT:
A method and apparatus for cleaning a surface of an optical element, such as germanium or silicon, of a larger arrangement, such as an infra-red camera. Cleaning liquid is applied to the surface and vibrated at a frequency to facilitate cleaning, such as 20-50 kHz. The invention is readily utilized in situations where the optical element frequently becomes dirtied such as in military equipment. A liquid container for the cleaning liquid has an outlet adjacent the surface to be cleaned. A vibrating device is also provided and may be directly on the surface or on a member adjacent thereto. The liquid is applied to the surface and the vibrator is actuated to vibrate the liquid to facilitate cleaning.
