Latest Patents

One of his latest patents is an "Apparatus for Surface Inspection." This innovative device allows for the non-destructive examination of entire surfaces for defects and contamination. It can detect microscopically small dot-shaped and linear defects, as well as extremely fine macroscopic non-homogeneous areas. The apparatus utilizes an astigmatic lens system placed in the optical path between a light source and an objective. This setup produces a cigar-shaped intermediate image, which is crucial for scanning the surface effectively. The device also features a dark-field stop assembly with an adjustable dark-field deflection system, ensuring precise light projection onto the surface being inspected. The reflected light is collected by a photo detector, and an electronic analysis system processes the signals to identify various types of defects.

Another patent by Sawatzki is also titled "Apparatus for Surface Inspections." This version includes an adjustable lens system that produces various intermediate images for different scanning purposes. The first scan uses a cigar-shaped intermediate image for a broad examination, while a second dot-shaped intermediate image is employed for detailed inspections of specific areas. Similar to his other patent, this apparatus also incorporates a dark-field stop assembly and an electronic analysis system for comprehensive defect measurement.
