UV-Vis-NIR External Diffuse Reflectance Accessories
The external DRAs available for the Cary 4000, 5000, and 6000i UV-Vis instruments take advantage of the photometric performance of the spectrophotometers for the highest accuracy and precision in materials analysis. The external DRA-900 (PMT), with exceptionally low photometric noise, wide photometric range, and good linearity, sets industry standards for research and reference work.
The external DRA-1800 (PMT/InGaAs) provides superior signal-to-noise and detection limits to give cleaner spectra with better resolution more quickly. The external DRA-2500 (PMT/PbS) hosts Cary 5000s PbSmart technology to extend the performance of PbS detectors. The PbS NIR detector is Peltier cooled and optimized in real time.
