Abstract:
The present disclosure relates to an optical arrangement for use in an optical imaging process. The optical arrangement includes an optical element, an immersion zone and a liquid repelling device. During the optical imaging process, the immersion zone is located adjacent to the optical element and is filled with an immersion liquid. The optical element has a first surface region and a second surface region. During the optical imaging process, the first surface region is wetted by the immersion liquid. At least temporarily during the optical imaging process, the liquid repelling device generates an electrical field in the region of the second surface. The electrical field being is adapted to cause a repellent force on parts of the immersion liquid which are responsive to the electrical field and inadvertently contact the second surface region. The repellent force has a direction to drive away the parts of the immersion liquid from the second surface region.

Claim (Index 42):
An optical element, comprising:\n an optical element body having first and second surface regions; and an electrically conductive element mechanically connected to the optical element in a region of the first surface region and/or the second surface region, wherein, during an optical imaging process performed using the optical element, the first surface region is wetted with an immersion liquid responsive to an electrical field.
