Title: Ewald Moersen: Innovator in Optical Materials

Introduction

Ewald Moersen, an accomplished inventor based in Mainz, Germany, has made significant contributions to the field of optical materials. With a remarkable portfolio of six patents, his work primarily focuses on innovative methods for determining local structures in optical crystals and growing large-volume oriented monocrystals.

Latest Patents

Among Moersen's latest patents is a groundbreaking method of determining local structures in optical crystals. This method involves observing schlieren visually in a material using divergent white light, followed by measuring the birefringence of polarized laser light to identify local defects within the material. The process ensures a spatial resolution of 0.5 mm or better. Furthermore, an interferometric measurement is conducted if the material proves suitable in the initial steps. This technique not only enhances the characterization of optical materials but can also be integral in the production of optical components for applications such as microlithography.

Another significant patent by Moersen details a method and device for growing large-volume oriented monocrystals. This technique entails heating crystal raw material in a melting vessel beyond its melting point to form a melt. By precisely lowering the temperature to the crystallization point, a monocrystal is formed at the bottom of the vessel. This innovative approach maintains a vertical axial temperature gradient and prevents heat loss through the vessel's side walls, allowing the monocrystal to grow towards the melt surface with a continuous phase boundary curvature radius of at least one meter.
