Kepler

KL4040FI

The KL4040 shares the same large area as the KAF-16803 CCD, but with a giant improvement in throughput, substantially lower noise, and higher quantum efficiency. The KL4040 has become an industry favorite for time-resolved applications such as space domain awareness.

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 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.
