Ultra SDDs
SDDs for High End Applications: Energy resolution at the theoretical limit
When ultimate spectral resolution is required, you should choose the highest performance available on the market. Based on our well-proven SDD droplet technology, our SD3plus detectors use the latest chip-integrated FET design to push the performance towards the physical limits.
The SD3plus Detector Performance
-
The ultra-low signal capacitances of the chip-integrated JFET offer outstanding low noise performance
-
Unmatched energy resolution values down to 121 eV @ Mn-Kα and 36 eV @ C-K
-
The outstanding energy resolution of our detector is especially apparent in light element detection where detector noise plays the largest role
-
Light element detection with superior performance can be achieved if SDDs are used as windowless detectors in high vacuum applications
-
Even Lithium K-line and Aluminum L-line can be well measured
-
The outstanding energy resolutions of the SD3plus detectors offer accurate quantitative analysis even for very low energy M- and L-lines and weak signals in low kV electron microscopy
-
The superior performance at warmer temperatures enables new possibilities for applications with low cooling power consumption; light element detection is possible even at room temperature
