KETEK's VITUS Silicon Drift Detectors (SDD)

General Description

KETEK's VITUS Silicon Drift Detectors (SDD) are the state-of-the-art X-ray detectors based on silicon substrate. Their typical X-ray energy range is between 0.2keV and 30keV. They are used in applications such as EDX, EDS, XRF, TXRF in bench top as well as in handheld based systems. Due to their wide operating temperature range they are especially suited for industrial and automotive applications.
