At the forefront of modern X-ray structure work, the mar345 Image Plate Detector System offers you the best choice for recording diffraction patterns of small molecules as well as protein crystals. Furthermore, it is a powerful tool for use in the fields of powder diffraction, texture analysis, small angle scattering, fiber and neutron diffraction. Since its introduction in early 1997 the impact in the scientific community has been extraordinary. Close to 500 instruments have been installed by beginning of 2023. They can be found at almost all synchrotrons around the world where they are used as work-horses for all kind of diffraction experiments. Likewise, they are very popular at both commercial and public research institutes. You won’t find an X-ray detector with a better price/performance ratio anywhere!

The patented read-out system combines a constant movement of the scanning head (driving down from the edge to the center of the plate) with an accelerated rotation of the plate. The actual rotation speed is inverse proportional to the current distance of the collection system to the center of the plate. This unique procedure of spiral readout ensures constant pixel read-out times over a large area of the plate. The maximum rotational speed of the plate is 3800 rpm.
The mar345s detector can be ordered in 3 variants, each one with a combination of 2 different scan modes:
a) 150 µm fine and 150 µm fast
b) 100 µm fine and 150 µm fast
c) 100 µm fine and 150 µm fine (standard mar345 detector)
