Title: The Innovative Mind of John E. Graebner
Introduction
John E. Graebner is a notable inventor based in New York, NY, USA, recognized for his significant contributions to the field of material science and optics through his four patents. His work has advanced the techniques employed in shaping polycrystalline diamond and has implications across various industrial applications.
Latest Patents
Among his latest patents, Graebner's innovative methods include a "Method of Shaping Polycrystalline Diamond," which describes a unique technique for selectively removing material from a polycrystalline diamond film's surface, resulting in a non-planar shape. This approach is particularly useful for creating polycrystalline diamond optical elements, such as convex or concave lenses and Fresnel lenses, including arrays thereof. The technique necessitates maintaining a suitably shaped hot template body in close contact with the polycrystalline diamond surface for a designated duration (ranging from 1 to 1000 hours) to achieve the desired features in the diamond surface. It employs a template body composed of rare earth metals, particularly Lanthanum (La) and Cerium (Ce), while the temperature must remain below the melting point of the template material. Additionally, another patent encompasses the etching of a diamond body, revealing that a diamond body, such as a CVD diamond film, can be effectively etched by immersing it in molten or partially molten metals like Lanthanum or Cerium.
