The beloved 512 × 512 EM-CCD sensor
provides over 90% peak QE.
High EM gain of maximum 1200×
EM gain feature is ideal for live cell imaging because of
shorter exposure times and reduced excitation light levels.

Low Noise
Minimal dark noise is another benefit of stable cooling performance
The dark current of a CCD depends on the temperature, and it decreases by half when the temperature drops by
approximately 7 to 8 ˚C. Therefore, cooling a CCD is a very good way to reduce dark current noise. The ImagEM X2's
stable cooling enables stable output and its water cooling minimizes dark current.
Highly stabilized control of sensor temperature with either water or forced-air cooling
Water or forced-air cooling is selectable for any application, and optimal cooling temperature can be set in each cooling mode.
Optimized sensor drive methods significantly reduce the clock induced charge (CIC)
Dark current consists of thermal charge and clock induced charge (CIC). CIC will dominate the dark charge in the
images taken at short exposure time, and thermal charge will dominate the dark charge in images taken at longer
exposures. The camera is adjusted to use the optimized drive method suitable to the scan speed. The biologist doesn't
have to think about CIC optimization for long or short exposures. The camera handles it automatically.
