PHOTON II: The Future of Detection is Now

Every photon diffracted from your sample provides a quantum of information that describes the crystal’s unique structure. Thus, the ideal detector must faithfully record each and every photon in order to preserve this precious information.

The new PHOTON II detector comes very close to this ideal, with speed, sensitivity, and accuracy superior to any other detector available in the home laboratory. By exploiting cutting-edge CPAD technology, the PHOTON II preserves each precious quantum of data to deliver a superior structure in less time.

The PHOTON II detector is available in two sizes. The PHOTON II 7 features an active area of 7 × 10 cm2 while the PHOTON II 14 comes with a monolithic 10 × 14 cm2 sensor. The D8 QUEST ECO, D8 QUEST & D8 VENTURE and a number of in-field upgrades for existing instruments take advantage of these detectors. Our new PHOTON III series introduces mixed-mode detection to the our in-house single-crystal X-ray diffraction solutions, using the technical principles originally developed for high-end synchrotron and XFEL beam lines.

  • Largest monolithic active area of up to 10 × 14 cm2
  • Quantum-limited sensitivity
  • Highest frame rate of any home laboratory detector
  • Eliminates the charge sharing noise that plagues current Hybrid Pixel Array Detectors (HPADs).
  • Excellent sensitivity over a wide energy range (Cu Kα to In Kα radiation)
  • No parallax, i.e. even at high incident angle, diffraction spots retain their true shape
  • Dead-time free shutterless data collection
