Title: Joseph T Foss: Innovator in Optical Filter Technology

Introduction

Joseph T Foss is a notable inventor based in Rochester, NY (US), recognized for his contributions to optical filter technology. With a total of 5 patents to his name, Foss has made significant advancements in the field, particularly in the manufacturing of optical transmission filters.

Latest Patents

Foss's latest patents include a method for manufacturing an optical transmission filter with extended out-of-band blocking. This innovative method fabricates a filter that accounts for the absorption effects of the filter material. The process is exemplified by the creation of an ultraviolet light transmission filter designed to transmit a specific band within the range of 230-320 nanometers. The resulting filter consists of multiple hard-coating, thin-film layers with alternating high and low indices of refraction. This improved filter offers high transmission rates, sharp edge slopes, and deep, extended out-of-band blocking. Compared to existing filters, it provides transmission rates that are up to three times greater, edge slopes that are four times sharper, and extended out-of-band blocking that reaches further into the visible range.

Another significant patent by Foss is for a low-cost filter for fluorescence systems. This filter is created by depositing a coating on a substrate, which may include several hard-coating layers. The coating has a transmission characteristic with a defined passband and extended blocking capabilities.
