About us

If you are not a scientist and you don't have a clue, what we are actually doing: we have a little video that explains in 2 minutes what X-ray crystallography is and what we do about it.

2015 OEM-partner for PILATUS3 and EIGER detectors by Dectris Ltd, Switzerland. Full detector support with mardtb goniometer
2014 Introduction of fast mar345= image plate detector and marYX2G data collection system
2014 marXperts GmbH is founded and purchases the rights for the mar345 detector, the mardtb goniostat systems and marmux data collections system from Marresearch GmbH. New owners of marXperts GmbH are Claudio Klein (managing director), Goeran Helgesson (managing director), Hong Wang (sales and service China) and Maik Neubacher (service director), long time staff members at Marresearch GmbH. The new company marXperts GmbH continues to sell and service the mar345 detectors and mardtb goniostats as well as the products of Rayonix, LLC.
2008 marUSA is renamed to Rayonix, LLC. New owners are Michael Blum and two minor co-owners.
2007 Introduction of the marmux complete data collection system consisting of a mar345 detector, a mardtb desktop beamline and a micro-focus generator (Xenocs or Incoatec)
2007 Introduction of the easymount add-on of the mardtb desktop beamline
2005 The co-founder Arno Lentfer leaves Marresearch
2003 marUSA introduces the marmosaic tiled CCD-detectors with either 2x2, 3x3 or 4x4 CCDs and 225mm, 300mm or 325mm square active surface, respectively
2003 Introduction of the marcsc crystallographic sample changer as an add-on to the mardtb desktop beamline
2002 X-ray Research GmbH changes its name into Marresearch GmbH, the trade name the company has been using for its products from the beginning
2001 Introduction of the mardtb desktop beamline goniostat equipped with fully automatic beam search and optimization capabilities
1998 Introduction of the marcam, an X-ray CCD-camera used for X-ray optics alignment
1997 Introduction of the first marccd CCD-detector developed by marUSA, Inc., a U.S. company owned by Michael Blum and Jules Hendrix
1996 Introduction of the mar345 image plate detector, a high speed system with a 345 mm diameter image plate and selectable pixel size. The read-out times of the detector range from 34 to 80 seconds.
1993 Introduction of the mar300 image plate detector, a system similar to the mar180 detector but with a 300 mm diameter image plate
1990 The company X-ray Research GmbH is founded by Jules Hendrix and Arno Lentfer. The company introduces the mar180 image plate detector as result of the development of an image plate detector for X-ray crystallography at the outstation of the European Molecular Biology Laboratory (EMBL) in Hamburg, Germany.
