What is an EMCCD?

The Electron-Multiplying C⁣C⁣D⁣ (E⁣M⁣C⁣C⁣D⁣) is a C⁣C⁣D⁣ camera to which is added a special electron multiplication output register. It is designed to practically eliminate the detrimental effect of the readout noise intrinsic to imaging devices, making them significantly more sensitive.

The readout noise generates false counts on a level comparable to a signal of a few photons. When the targeted real signal is close to or lower than this noise limit, it cannot be reliably identified by the camera. By amplifying the signal up to several thousand times with E⁣M⁣ ⁣G⁣a⁣i⁣n⁣, E⁣M⁣C⁣C⁣D⁣ cameras make the readout noise effectively negligible. E⁣M⁣C⁣C⁣D⁣s⁣ thus can offer ultimate sensitivity for the observation of the darkest scenes, down to a signal of a single photon.

E⁣M⁣C⁣C⁣D⁣s⁣ also support faster frame rates than their C⁣C⁣D⁣ counterparts, making them highly suitable for real-time imaging. Nüvü™ has completely reinvented E⁣M⁣C⁣C⁣D⁣ electronics to further reduce any other noise sources, such as t⁣h⁣e⁣r⁣m⁣a⁣l⁣ ⁣n⁣o⁣i⁣s⁣e⁣ and clock-induced charges, allowing for unmatched sensitivity.
