This version of the ML4710 uses a back-illuminated sensor on deep depletion silicon for enhanced near infrared sensitivity. Deep depletion silicon has substantially higher dark current than standard silicon.
Quantum efficiency (QE) measures how effectively a detector converts incoming photons into electrons. In our graphs, QE is expressed as a percentage. A sensor’s QE typically varies based on its architecture, coatings, and materials. High QE remains a crucial consideration for applications such as astronomy, space debris imaging, and life science research.
