Advanced optical filters are improving laser-based satellite communications by enabling ‘more signal and less background.’Rapid, on-demand access to information is a necessary facet of daily life in the present “age of communications.” The reliable communication links that society necessitates support person-to-person and device-to-device communications at any time and, increasingly, in any place. Such assurances of connectivity owe to the massive technological strides of the past half century.

Raman systems continue to evolve — from benchtop scientific instrumentsb to portable analytical devices that are used in biomedical applications, with optical filters playing a critical role. While Raman spectroscopy has long been useful in pharmaceutical analysis and the identification of hazardous materials, the technology’s usefulness in biomedicine has also been expanding due to less bulky, miniaturized instrumentation.
