ImagEM X2 EM-CCD Camera
The ImagEM X2 is an extremely versatile camera that quietly delivers 70 frames/s at full frame and up to 1076 frames/s with analog binning and regions of interest. With very high signal to noise in the near dark conditions, extremely low dark current and global shutter, the ImagEM X2 enables quantitative ultra-low light imaging both for long integration times and at high speed. With EM gain off, the extremely deep full well capacity can extract information from the lowest contrast bright images. Additional new features allow for optimized camera triggering, on-board shuttering for capture of truly dark reference images, streamlined connectivity through IEEE1394b, improved overall signal to noise and increased non-EM dynamic range. Hamamatsu has taken the beloved 512 × 512 EM-CCD sensor and created a masterfully redesigned camera that delivers maximum speed and precision performance.

Hungry for Photons
With large pixels, high QE, and relatively zero read noise, EM-CCD technology performs in low light conditions. How low light? When you've got fewer than 10 photons per pixel (i.e. the dimmest of the dim samples) between the sample and background, EM-CCDs are the perfect tool for the job, delivering the best SNR of any camera technology. For high mag, biologically relevant applications with routine exposure times of 10 ms to 30 ms, the sample is likely emitting 100 s to 1000 s photons per pixel. But with faster speeds come shorter exposure times, risking the ability to capture more than 10 s of photons per pixel in one shot and therefore pushing the application into the ultra-low light zone. The ImagEM X2 makes these super-fast exposures possible and has the sensitivity to provide visually pleasing and quantitatively meaningful images in a photon-starved environment.
