What are the EMCCD’s optics?

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.

 

Though generating less noise goes a long way to increase a camera’s sensitivity, an important part of the equation is also to maximize how efficiently each photon received by the E⁣M⁣C⁣C⁣D⁣ is converted to signal on the image. The key to achieving this goal is to carefully consider the different components interacting with light inside the camera; the sensor and the optical window.
