ImagEM X2-1K EM-CCD camera: C9100-24B

The ImagEM X2-1K (C9100-24B) is an extremely versatile camera that quietly delivers 18.5 frames/s at full frame and high sensitivity (1024×1024 pixel). With very high signal to noise in near dark conditions and extremely low dark current, the ImagEM X2-1K 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 1024 × 1024 EM-CCD sensor and created a masterfully redesigned camera that delivers maximum speed and precision performance.
