Fast optical camera for time stamping of optical photons

The TPX3CAM is a fast optical camera for time stamping of optical photons. It is based on a new silicon pixel sensor. In combination with the Timepix3 ASIC and readout it is suitable for a wide range of applications which require time-resolved imaging of electrons, ions, neutrons or single photons. The camera can be easily integrated both in table-top lab setups, as in synchrotron or free-electron-laser environments.


  • Velocity Map Imaging (VMI)
  • Single Photon Imaging
  • Mass Spectrometry Imaging (MSI)
  • Neutron Imaging
  • Atom Probe Tomography (APT)
  • Phosphorescence Lifetime Imaging Microscopy (PLIM)
  • Fluorescence-Lifetime Imaging Microscopy (FLIM)
  • Angle-resolved Photoemission Spectroscopy (ARPES), time-resolved ARPES


Simultaneous Imaging

Image below: TPX3CAM can simultaneously image and time-stamp light flashes of more than 1000 photons with high quantum efficiency in the 400 to 1000 nm wavelength range. It can efficiently register ions impinging on an MCP (micro-channel plate) in the VMI (velocity map imaging) configuration. The MCP is coupled to a fast P47 phosphor, which produces light flashes in response to ions hitting the MCPs. The TPX3CAM, placed outside of the vacuum, can detect light flashes from the phosphor.

Benefits of the detector

  • 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

Case Statement

"We use the TPX3CAM for measurements of electrons and ions in our velocity map imaging apparatus. The ns time resolution and data acquisition rate allow us to make measurements in ways that were not possible before. We are very happy with the camera performance.”
