  • Method and apparatus for preventing debris contamination of optical elements used for imaging
    Patent number: 7044610
    Abstract: The imaging debris produced by imaging a media with a higher power laser is prevented from accumulating on an optical imaging element by establishing a substantially non-turbulent fluid flow across the optical element. The non-turbulent flow forms a barrier between the optical element and the imaging environment such that debris is not able to reach a surface of the optical element during an imaging operation.
    Type: Grant
    Filed: February 10, 2003
    Date of Patent: May 16, 2006
    Assignee: Kodak Graphic Communications Canada Company
