The EIGER2 detector is the latest masterpieces of DECTRIS AG. It features a newly designed sophisticated read-out system with dual energy discrimination that effectively suppresses background and improves signal-to-noise. Two analog circuits allow for simultaneous read and write operation with NO DEADTIME!  The EIGER2 detectors have a small pixelsize of only 75 microns (PILATUS3: 172 microns) and hence a larger amount of pixels as compared to a PILATUS3 detector of the same physical dimension. 

marXperts now also offers full support for the EIGER2 series of detectors with our mardtb goniostat. In fact, the EIGER2 detectors are the perfect fit for the mardtb and data collection is fully integrated into our well-known data collection software.



Extremely short read-out time of < 1 μsec allows for fine φ-slicing and shutterless data collection.


Very small pixels of only 75 μm


Extremely high, no point-spread due to direct conversion leading to small spots with better I/σ


Virtually no read-out noise


Virtually unlimited (32-bits)


mardtb desktop beamline with Eiger R 4M detector
The EIGER2 R 4M or 1M detector is mounted on a mardtb goniostat. The mardtb  “desktop beamline” features a fully automatic beam alignment system and more than 10 motors including an “inverted PHI” assembly and a 2-theta stage. The system can be operated with any X-ray source (sealed tubes to synchrotrons).
marmuX2G Data Collection System marYX3G:
An EIGER2 R 4M or 1M detector with a mardtb goniostat in combination with a marµX microfocus generator. This system is the perfect choice, when cost-of-ownership and maintenance issues come into play. Despite of the low price, the system is highly suitable for fast screening experiments, but also for complete data collections of small crystals and other kinds of diffraction experiments.
Excillum MetalJet X-ray source metaljet:
 If you are aiming for the ultimate performance in the home lab, a combination of a MetalJet X-ray source with a EIGER2 R 4M detector and a mardtb goniostat is the very best you can obtain today. Excillum's patented MetalJet technology beats any other conventional X-ray source in terms of brilliance and is a true alternative to a synchrotron. Please contact us for further details!

UPGRADE OF  mar345dtb

Existing mar345dtb detector sytems can easily be upgraded with an EIGER2 detector, i.e.  the mardtb can be used together with the EIGER2 R 4M or 1M detector. Due to its larger detector surface that eliminates requirements for collecting multiple data sets at 2-theta offsets, the EIGER2 R 4M detector clearly is your first choice.  When  using the small EIGER2 R 1M detector, it is possible to mount the detector in front of the mar345 detector. One can then easily take away the small EIGER2 detector and use the large mar345 image plate detector if there is a need for a large detector surface. For this special combination the range of movement of the distance translation stage of the mardtb goniostat is 22 to 150 mm for the EIGER2 R 1M detector and 120 to 425 mm for the mar345 detector.


An exiting experiment has been done with a mar4M system consisting of the EIGER(1) R 4M detector and a mardtb goniostat. The setup has been used to collect  a complete data set of a large protein with 350 amino residues to high resolution (1.5 Ang.) in just 30 minutes with extraordinary quality. Please see the application note AN07Sep17 for further details.
