Title: David Michael Williamson: Pioneering Optical Innovations in Tucson, AZ

Introduction

David Michael Williamson, based in Tucson, AZ, is a distinguished inventor with an impressive portfolio of 26 patents. His work primarily focuses on advancements in ophthalmic systems and optical technology, contributing significantly to the fields of optics and vision correction.

Latest Patents

Williamson's latest patents include groundbreaking innovations such as the ophthalmic optical system, ophthalmic objective lens, and ophthalmic device. The ophthalmic optical system is engineered to apply an angular scanning light ray to the eye. It defines the modulation M as the ratio of the output angle to the input angle, where ωin represents the angle of the incident light ray to the system's optical axis, and ωout signifies the angle of the exiting light ray. This system adheres to the conditional expression Mpar

Another notable invention is an optical objective designed for operation within the extreme ultraviolet (EUV) spectral region. This catoptric system features a reference axis and includes three reflectors. The first reflector holds a pattern-source with a substantially one-dimensional pattern. The second and third reflectors are configured to create an optical image of the pattern, achieving a demagnification coefficient greater than one for extreme UV light while utilizing only two light beams originating from the first reflector.
