Electron Multiplying Camera - iXon Back Illuminated Document

It is fundamental that a back-illuminated sensor is housed in a hermetically sealed permanent vacuum head with minimized out-gassing, otherwise both cooling performance and the sensor QE will steadily degrade. It is this compelling reason that drove Andor to develop UltraVac.

Andor's proprietary UltraVac process has a proven track record of field reliability, accumulated over more than 10 years of shipping high-end vacuum cameras. UltraVac also enables use of only one input window, improving photon-throughput by 8%.
