Title: Holger Wenz: Innovator in Optical Examination Technologies
Introduction
Holger Wenz is a notable inventor based in Ludwigshafen, Germany. He has made significant contributions to the field of optical examination technologies, holding a total of 2 patents. His work focuses on devices that enhance the inspection and handling of sensitive flat objects, particularly wafers.
Latest Patents
Wenz's latest patents include a "Holding and turning device for touch-sensitive flat objects." This innovative device features a distance positioning mechanism that holds the object perpendicular to its plane at a defined distance. It also includes a lateral positioning device that allows for precise positioning and rotation of the object without contact. The rotational drive is coupled with the lateral positioning device, providing the necessary force for rotation while ensuring that the distance positioning device remains stationary.
Another significant patent is the "Inspection device and inspection method for the optical examination of object surfaces, particularly of wafer surfaces." This device employs dual illumination systems to enhance the optical examination of surfaces. The first illumination device utilizes a laser to illuminate a specific measurement point, while the second device illuminates the same point with a broader image spot using light of lower coherence. This method allows for the detection of irregularities on the object surface through a scattered light detector operating in a dark field.
