Abstract

Electrostatic techniques can be used to keep dust and aerosols from depositing on optical components. The system makes use of a corona discharge and a safety screen, located out of the optical path, to charge the incoming dust and then push it away from the optical surface. The system is effective for the dust particles normally found in the atmosphere, there are no exposed high voltage components or moving parts, and power consumption is quite limited.
