"Webbdetector; in other words, it’s a measure of the weakest optical signal that can be detected. Therefore, it is desirable to have an NEP as low as possible, since a low NEP value corresponds to a lower noise floor and therefore a more sensitive detector. Even at higher input intensities, a low NEP is beneficial since it will lead " - Ingaas detector sensitivity curve
