電子計數直接偵測數位影像系統


型號:K2
規格:CMOS
技術文件:尚未上傳
廠商:Gatan

Features 

“At present only the Gatan K2, when operated in counting mode, can produce a DQE(0) as high as 80% in conjunction with reasonably small exposure times.  The K2 detector frame rate is about 10 times higher than that available with the two other detector brands.”– Subramaniam, S., Kuhlbrandt, W. & Henderson, R. (2016). IUCrJ 3, 3-7.

The K2 Summit® electron counting direct detection camera is simply the highest performance detector available for cryo-electron microscopy (cryo-EM). The unmatched frame rate of this direct detector allows electron counting modes to improve both contrast and resolution for large and small molecules alike. 

  • Only the K2 Summit can produce a DQE as high as 80%
  • First to identify ground-breaking structural discoveries using cryo-EM
  • K2® XP sensor provides the highest performance sensor for both resolution and contrast
  • Superior detective quantum efficiency (DQE) means better science
    • Image samples below 500 kDa at high resolution
    • Reliably resolve differences with heterogeneous samples
    • Higher quality cryo-tomography
  • Super-resolution mode means 4x larger area in one image
