Photon counting is a technique in which individuals photons are detected. Axiom Optics offers a wide range of cameras sensitive enough to offer photon counting capability. The most well known camera solution technology for photon counting applications is EMCCD – we offer a range of EMCCD cameras, including high-speed EMCCD cameras (OCAM).

The recently released ORCA-Quest qCMOS is a new type of sensor offering even better than photon counting: photon number resolving. Photon number resolving is the ability to resolve the exact number of photoelectrons, and is achieved by reducing the noise of the camera to almost zero! Photon number resolving is the ultimate in quantitative imaging.
