Advanced Spectral Measurement Systems And Semrock Optical Filters

By Michael Delay, PhD and Anne Souchon

The evolution of optical thin film deposition technology and filter design has propelled the production of intricate and optimized optical filters, addressing the escalating demand for superior performance. IDEX Health & Science, through its Semrock optical filters, has been at the forefront of this innovation. As the demand for more rigorous spectral specifications grows, necessitating advanced visual blocking levels and steep spectral edges across UV to NIR wavelengths, the need for specialized measurement tools becomes imperative.

This white paper provides a comprehensive overview of the proprietary spectral measurement systems (SMS) developed by IDEX Health & Science, with a focus on the established Peregrine and the recently introduced KolaDeep Spectral Measurement Systems. The discussion encompasses the challenges posed by commercially available spectrophotometers, the novel capabilities of the KolaDeep SMS, and the technology enhancements in the Peregrine SMS. Through detailed examples and measurements on various optical filters, examine how these advanced SMS platforms ensure precise and reliable spectral measurements, especially in scenarios involving deep blocking and steep spectral edges.
