The Quantum Efficiency (QE) of an imager is an important parameter because it has a significant impact on the sensitivity of a camera at a particular wavelength of interest. However, one should not use it as the sole determinant in camera selection: it should be considered in the full context of the application.
The following knowledge base articles provide insight into the other relevant factors, such as pixel size, read noise and dark-shot-noise. When selecting a camera it is important to consider how these parameters determine the image quality that one can expect for different camera exposure settings under low-light and bright-light conditions.

The graphs provided in this section are an estimate of the spectral response of the imager, based on information that is available from various sources. This data is not provided by the imager manufacturer, nor was it obtained by measurement in the cameras referenced on this site.
