EMCCD

Dose determination of single grains on multi grain aliquots by spatially resolved luminescence provided by a state-of-the-art electron multiplying CCD camera (EMCCD)

Spatially Resolved Single Grain Analysis using EMCCD

  • UV to NIR (200 – 1050 nm) image detection for spatially resolved / single-grain measurement

  • operational at the TL/OSL or RF measurement position

  • 512 x 512 pixel back-thinned, UV-coated EMCCD chip (electron multiplying – EM - technology), 16 bit resolution, frame – transfer format

  • operates also in traditional CCD mode (low noise)

  • max. frame rate: > 33 frames/second (full frame)

  • gigabit Ethernet data interface

  • high quantum efficiency from UV to NIR : approx. 50% @ UV Quartz OSL emission peak; approx. 85-90 % @ all VIS Quartz/Feldspar emission peaks; approx. 60% @ potassium feldspar NIR RF peak (865 nm)

  • ~8 mm diameter sample is imaged on the camera chip (ca. 16 μm / pixel)

  • incl. electromechanical shutter

  • TE cooling min. -95 °C (-70 °C guaranteed for life), thermostatic precision ± 0.05°C

  • integration into lexsyg measurement control software
