Large SDDs
Large SDDs for high detection efficiency
To increase the detector collection efficiency, PNDetector developed different SDD sensors with large detection areas and optimized geometries. With our unique and unrivalled designs solid angles exceeding 1 sr can be achieved with single channel SDDs.
Large areas - great efficiency
-
Excellent energy resolution down to 125 eV @ −30 °C or 123 eV @ −40 °C
-
The superior energy resolution enables light element detection down to Lithium even with 100 mm2 SDDs
-
Due to our long lasting experience in packaging, we can offer extremely compact and application-oriented module packages, with chamfered caps
-
Small modifications can lead to big changes – to achieve the best fit request a proposal for a customized solution tailored to your system
