Title: Paul Richard Ehrmann: Innovations in Optical Etching and Materials Polishing

Introduction

Paul Richard Ehrmann is an inventor based in Hughson, California, whose work includes innovations in optical etching and materials polishing. He is associated with Lawrence Livermore National Security, LLC, and holds 2 patents.

Latest Patents

Ehrmann’s patent, “Etching of Water-Sensitive Optics with Water-in-Oil Emulsions,” describes a method for etching an optic using a microemulsion. The microemulsion contains a continuous oil phase, a surfactant system, and water. The method submerges at least part of the optic in the microemulsion and agitates it with ultrasonication to etch the surface.

His patent, “Method and System for Polishing Materials Using a Nonaqueous Magnetorheological Fluid,” concerns a polishing fluid made with a primarily organic carrier liquid and magnetizable particles. The fluid also contains a buffer, a stabilizer, and water, and has a pH between 6.5 and 9.0.

Career Highlights

Ehrmann’s patented work addresses specialized processes for treating optical and other materials. His inventions apply microemulsion-based etching to water-sensitive optics and nonaqueous magnetorheological fluids to materials polishing.

Collaborations

Ehrmann’s listed coworkers include Marlon G. Menor and Ted Alfred Laurence. His association with Lawrence Livermore National Security, LLC, provides an organizational context for his patent work.

Conclusion

Paul Richard Ehrmann’s two patents reflect focused contributions to optical etching and materials polishing, combining specialized fluid formulations with practical processing methods.
