DECTRIS PILATUS4 For Laboratories

With their high quantum efficiency (greater than 95%) and their large active area of up to 155 x 162 mm, PILATUS4 R CdTe detectors enable fast data collection using any X-ray source from Cu to In. In particular, for Mo, Ag, and In radiation, PILATUS4 R CdTe outperforms any HPC detector with a Si sensor – even PILATUS3, which has the thickest Si sensor available. And for instruments that primarily use Cu or Ga radiation, our PILATUS4 detectors with Si sensors deliver the same great performance.

A dynamic range spanning ten orders of magnitude is achieved through PILATUS4’s superior count rates and the absence of any detector background. Internal frame rates of up to 200 Hz improve the count-rate correction and ensure highly accurate measurement of strong intensities. With four energy-discriminating thresholds, PILATUS4 offers new possibilities in Laue diffraction and spectral imaging.

Large & efficient: Active areas of up to 155 x 162 mm, with more than 95% quantum efficiency
High dynamic range thanks to zero detector background, superior count rates, and simultaneous read/write.
Versatile: High quantum efficiency from Cu to In; four energy-discriminating thresholds for polychromatic applications
