Title: The Innovations of William A. Meredith, Jr.
Introduction
William A. Meredith, Jr. is an accomplished inventor based in Santa Rosa, CA (US). He is known for his significant contributions to the field of optical engineering, particularly in the development of advanced filtering technologies. His innovative work has led to the creation of a unique type of absorbing dichroic filters that have various practical applications.
Latest Patents
Meredith holds a patent for "Absorbing Dichroic Filters." This invention features high purity (95-99.5 percent) red, orange, and yellow filters that consist of a periodic stack of relatively low index of refraction dielectric material, such as SiO₂ or MgF₂, combined with absorbing materials like silicon or Fe₂O₃. The design allows for a high index ratio, typically ranging from 1.7 to 2.5. Despite having only 5 to 7 layers, these filters deliver optical performance comparable to all-dielectric filters with 30 or more layers. They achieve color purity that is unattainable by traditional all-dielectric filters while maintaining a simple and cost-effective design. Additionally, these filters exhibit low stress levels and effectively absorb and reflect unwanted light, such as blue light. This makes them ideal for coating on flexible substrates like plastics and for use in lamp envelopes, particularly for red or yellow bulbs in automotive applications.
