The cadmium-telluride sensor of DECTRIS EIGER2® R CdTe X-ray detectors offers a higher quantum efficiency for molybdenum (Mo), silver (Ag), and indium (In) compared to these detectors’ silicon-sensor counterparts, while closely matching silicon detectors’ high efficiency for copper (Cu) radiation. The series’ unprecedentedly high count-rate capability, which is enabled by DECTRIS’ patented Instant Retrigger, allows for more accurate measurements of even the highest intensities that can be achieved with laboratory sources. Equipped with two energy-discriminating thresholds, these detectors have low dark counts from environmental background. This significantly improves the signal-to-noise ratio for weak signals and long exposures, allowing for shorter measurement times and better data quality. Single-photon counting, in combination with continuous read/write, overcome all saturation issues and the limited dynamic range of integrating detectors. In addition, direct detection and the small, 75-µm pixel size guarantee high spatial and angular resolution.
Coming in five different sizes, which include wide geometries, and with optional vacuum compatibility, EIGER2 R CdTe detectors can fulfill the requirements of almost any high-energy experimental setup you can think of.
- Fast & precise: these detectors feature high frame and count rates, a high dynamic range, the best signal-to-noise ratio, and dead-time-free readouts.
- More & better data: our detectors offer the highest possible quantum efficiency for shorter measurement times and better data.
- Versatile: the detectors come in many sizes and geometries, with room-temperature operation and optional vacuum compatibility.
Detectors
EIGER2 R CdTe 4M
This is the largest commercially available laboratory detector with a cadmium-telluride sensor. It is particularly well-suited for high-energy or dual-wavelength single-crystal diffraction (SCD) and SAXS/WAXS.
EIGER2 R CdTe 1M
This is the ideal detector for excellent data quality and outstanding productivity in high-energy SCD and SAXS/WAXS applications.
EIGER2 R CdTe 500K
This detector will be an upgrade over any other scientific instrument for high-energy single-crystal or X-ray powder diffraction, SAXS/WAXS, and microCT Imaging.
EIGER2 R CdTe 2M-W
This is the widest high-energy detector in our hybrid-pixel portfolio. It is well-suited for giving you a panoramic view of high-energy powder X-ray diffraction, pair distribution function studies, and total scattering measurements.
EIGER2 R CdTe 1M-W
This is a wide-area photon-counting detector for high-energy powder X-ray diffraction, pair distribution function studies, and total scattering measurements.
