KL4040BI

For years we dreamed of a back-illuminated version of the KAF-16803 CCD, and here it is, with high throughput and lower noise. The KL4040BI offers sensitivity comparable to a CCD42-40 with about 1.8x the sensor area.

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.
