With a total of four patents to her name, she has developed innovative solutions that enhance safety in environments where laser exposure is a concern.

Latest Patents

One of her latest patents is for glasses designed for laser protection. This invention focuses on producing cuprous halide- or cuprous-cadmium halide-containing glass articles that are nearly completely opaque to ultraviolet radiation. These glasses can also be opaque to radiation with wavelengths up to 550 nm while remaining transparent to visible light. The method involves exposing the glass articles to a hydrogen gas-containing atmosphere at temperatures between 375°C and 500°C for at least 18 hours. This process develops an integral reduced layer on at least one surface of the article, effectively preventing the transmission of harmful ultraviolet radiation.

Another notable patent is for laser eyewear protection. This invention produces glass articles that are transparent to visible radiation but opaque to ultraviolet radiation. This feature makes them particularly suitable for protecting wearers from exposure to laser radiation in the ultraviolet regions of the electromagnetic spectrum. The method for creating these articles involves exposing silver halide-containing glass to flowing hydrogen in a heat chamber operating at 375°C to 500°C for a minimum of four hours. This process results in an integral reduced layer that prevents ultraviolet radiation from passing through the articles.
