EIGER2 R series

EIGER2 R detectors come with a choice of CdTe or Si sensors. For those cases where higher-energy (e.g., Ag) radiation is primarily used, e.g., high-pressure or charge-density research, CdTe sensors allow researchers to shorten experiment times providing data of equivalent quality to the well-established Si sensors but in less time.

On Rigaku instruments, EIGER2 R is offered in 2 sizes: The EIGER2 R 1M (active area: 77.2 mm x 79.9 mm) and EIGER2 R 4M (active area: 155.2 mm x 162.5 mm). The EIGER2 R 1M is typically offered as a CdTe detector for small molecule crystallographers whereas the EIGER2 4M is generally used for applications where wide coverage is needed in a flat detector configuration, e.g., macromolecular crystallography. The EIGER2 R detectors deliver high count rates with continuous readout, achieving duty cycles greater than 99% thanks to a global electronic shutter. The EIGER2 R 1M and 4M detectors have small (75 μm) pixels with a single pixel point spread function to provide superior resolving power for reflections from samples with long unit cells, like macromolecules. Smaller pixels mean closer detector distances are possible which in turn means more data per image and faster experiments.
