A camera with quantitative complementary metal oxide semiconductor (qCMOS) image sensor. The qCMOS camera reaches the physical limit: reliable quantification of photon numbers within each pixel, eliminating the influence of technology on the “triangle of frustration” (resolution, sensitivity, speed).
Please refer to this link, if you would like to investigate the qCMOS camera further.
The ratio of incoming photons converted into photoelectrons inside of the detector. It is usually represented in percentage and varies with wavelength. For example, a QE of 70% means that 70 of every 100 incoming photons are converted to photoelectrons. Many factors of pixel design determine the QE.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
