Title: Mark E Koehler: Innovator in Photogoniometric Analysis and Particle Size Determination
Introduction
Mark E Koehler is a notable inventor based in Middleburg Heights, OH (US). He has made significant contributions to the fields of photogoniometric analysis and particle size determination, holding a total of 2 patents.
Latest Patents
Koehler's latest patents include a "Method and apparatus for photogoniometric analysis of surfaces." This invention features a photogoniometric instrument that utilizes a light source to provide a collimated beam of light illuminating a test surface. A light detector is mounted for rotation around the point of intersection of the illuminating beam on the test surface. The detector is driven by a motor through a range of reflectance angles, while a microcomputer digitizes the detector output periodically, storing the data in its memory. This data defines a photogoniometric curve, which includes both specular and nonspecular portions. A host computer receives this data, deconvolutes it into spectral and diffuse portions, and analyzes them separately.
Another significant patent is the "Disc centrifuge photosedimentometer." This apparatus is characterized by a motor and a transmission, enabling precise power interruption for accurate particle size determinations. This device enhances the accuracy of determining particle size and size distribution.
