ImagEM X2 EM-CCD camera C9100-23B

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 near dark conditions and extremely low dark current, 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 for EM gain protection, 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.
The ImagEM X2-1K(C9100-24B) 1024×1024 version is also available.
