TEM & SEM Imaging Spectroscopy


The TPX3Cam is a fast optical camera for time stamping of optical photons. It is based on a new silicon pixel sensor, which in combination with the Timepix3 ASIC and readout, is suitable for a wide range of applications which require time-resolved imaging of electrons, ions or single photons. The TPX3Cam can be easily integrated both in table-top lab setups, as in synchrotron or free-electron-laser environments.

Benefits of the TPX3Cam

  • Increased light sensitivity silicon sensor
  • Wave length range: 400 – 1000 nm
  • Per pixel simultaneous detection of time (ToA) and intensity (ToT)
  • Time resolution 1.6 ns, effective frame rate > 500 MHz
  • Lossless, data driven readout up to 80 Mhits/s
  • Flexible optical design outside of vacuum

LynX (X-ray)

The LynX detector series are hybrid pixel area detectors based on the Timepix/Medipix3/Timepix3 technology. They have a pixel pitch of 55 µm, suitable for a wide range of applications. The capability of the LynX detectors to discriminate or measure energy of X-rays in each of its 512×512 pixels offers excellent performance for X-ray detection, imaging and tomography. The detectors consist of a sensor (Si, GaAs, CdTe), which is divided into an array of pixels. Each pixel is connected with miniature bump-bonds to the readout ASICs below the sensor. Go to our applications and/or publications page to find out more.

Benefits of LynX

  • Direct, single photon detection
  • Increase point spread function in charge summing mode
  • Zero noise, high S/N and high dynamic range
  • Short read out time and high frame rates
  • Modular detectors, enabling large active area
  • Increased high energy efficiency with high Z sensor materials

Lynx 120 - LynX 120 is based on the Timepix ASIC. Each pixel either counts the number of detected events, measures the amount of energy deposited in the pixel or measures the time of arrival of the detected photon. The readout provides frame rates up to 120 frames/s.

LynX 1800 - LynX 1800 is based on the Medipix3RX ASIC and has improved speed. In continuous read out mode up to 1800 frames/s with zero dead time can be recorded. In charge summing mode improved spectroscopic performance is achieved, avoiding loss of energy because of pixel to pixel charge sharing. In addition, the LynX 1800s, which is also based on Medipix3RX, but with bumps every 110 µm is also available. In charge summing mode, it has 4 energy thresholds allowing to count X-rays in different energy windows in a single measurement.

Cheetah (Electron Microscopy)

ASI’s Cheetah is a hybrid pixel detector suitable for electron microscope applications. The sensitivity and speed of Cheetah offers unprecedented possibilities for electron diffraction, imaging and tomography. Scintillated detectors do not have the signal to noise ratio’s that can be obtained with the Cheetah. Other direct electron cameras lack the dynamic range the Cheetah has and are too beam sensitive to be used for diffraction experiments. The Cheetah’s high speed makes it ideal for looking at dynamic processes and catching fast fading signals.

Benefits of the Cheetah

AAI offers three different versions which mainly differ in size and speed. The table right shows the comparisons between the three options. All cameras have the following properties:

  • Single electron sensitivity
  • Zero readout noise, high Signal to Noise
  • High dynamic range
  • Background noise suppression through threshold
  • Short readout times and high frame-rates
  • Increased high energy performance with high-Z sensor material
