Abstract
Advancements in optical coating methods developed at the Jet Propulsion Laboratory (JPL) now allow for spatial optimization of detector response with respect to a spectrometer system’s optical dispersion. When combined with JPL’s delta-doped, UV detector technology, these patterned coatings will reduce the complexity required for UV instruments while also improving throughput. This technology development offers an innovative solution to the limitations and compromises inherent in existing UV coating technologies. This advancement will result in detectors with high quantum efficiency (QE) in targeted wavelength bands, allowing for more versatile UV–Visible instrumentation.
