We have four types of detectors commonly available for use:
A “narrow-band” mercury cadmium telluride (MCT) from Bruker (MCT-D313)
Cut-off 750 cm-1
A “mid-band” MCT from Bruker (MCT-D316)
Cut-off 600 cm-1
A “wide-band” MCT from Bruker (MCT-D315)
Cut-off 420 cm-1
A focal plane array (64 × 64)
Unless otherwise requested, the standard configuration of the beamline uses the narrow band MCT detector.
Figure: Bruker detector performance. Note the order of magnitude decrease in “detectivity” with the wide-band detector compared to the narrow- and mid-band detectors.
