iXon^EM+ EMCCD Camera

888

The iXon^EM+ DU-888 back-illuminated EMCCD has single photon detection capability without an image intensifier, combined with greater than 90% QE of a back-illuminated sensor. Containing a 1024 x 1024 Frame Transfer CCD sensor from E2V Technologies, it enables charge to be multiplied on the sensor before it is read out, while utilizing the full QE performance of the CCD sensor. The absolute EMCCD gain of the camera can be varied linearly from unity up to a thousand times directly through the software, via a true quantitative EM gain scale. Andor are the first to offer this technology as a complete, software controlled system for scientific digital imaging applications. The system offers up to 10 MHz pixel readout rate, both EMCCD and conventional amplifier outputs and benefits from minimized dark current with unequalled thermoelectric cooling down to -95°C.
