Quantum Efficiency
Quantum efficiency (QE) measures how effectively a detector converts incoming photons into electrons. In our graphs, QE is expressed as a percentage. A sensorās 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.
