Abstract

See full text

A scraper for an optical surface of a device is disclosed. The scraper includes a blade having an edge that is rigid and non-deforming to withstand high shear stresses. The blade is configured to rotate about a first axis parallel to the optical surface and also configured to move in a line with respect to a second axis perpendicular to the optical surface. This allows the rigid, non-deforming blade to maintain contact with the optical surface. Furthermore, the edge is configured to move across the optical surface to remove any materials adhered to the surface. The scraper can be used to clean the optical surface of an instrument, for example.
