Problems solved by technology

[0003] Optical instruments operating during crystallization or granulation processes that undergo particle growth (such as, but not limited to, particle-scale characterization scanners), often have their optical performance degraded by deposition of particles on their outer windows
This deposit is often so rigidly attached to the window that squeegee and brush type wipers cannot remove the particles from the window

Embodiment Construction

[0041] While exemplary embodiments have been shown and described, it will be appreciated that various changes may be made therein without departing from the spirit and scope of the invention.

[0042] Embodiments of the present invention relate to wipers for windows, including but not limited to the process-side optical surface of the window. As used herein, optical surfaces are found in, but not necessarily limited to, optical instruments.

[0043] A window may be any surface that collects, attracts, or accumulates particles or any other type of material. For example, applications in which embodiments of the window wipers disclosed herein may be employed include particle handling, such as in the pharmaceutical field, where binders such as cellulose and lactose may accumulate on the instrument. However, other applications for the disclosed window wipers are possible, such as, but not limited to, any instrument, sensor, device, and surface employed in chemical processing and m...

Abstract

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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application 61 / 036333, filed March 13, 2008, which is hereby incorporated by reference in its entirety. Background technique [0003] Optical instruments operating during crystallization or granulation processes undergoing particle growth, such as but not limited to particle-scale characterization scanners, often have their optical performance degraded due to particle deposition on their outer windows. This deposit is often so rigidly attached to the window that squeegee and brush type wipers cannot remove the particles from the window. [0004] Accordingly, an alternative is desired to overcome the problems associated with the use of conventional brush-type wipers and squeegees. Contents of the invention [0005] This Summary introduces in a simplified form a selected group of concepts that are further described below in the Detailed Description. This Sum...
