EDAX has announced the new Lambda wavelength dispersive spectrometry (WDS) series. This utilises a combined hyperbolic–parabolic HCO optical design with a polycapillary transmitter to optimise X-ray optics across a wide energy range. It is supplied with a complete and fully customised set of diffractors. Lambda spectrometers do not require a dedicated WDS port and, having a compact geometry, they are compatible with additional detectors installed on the same SEM. The spectrometers are fully integrated with Energy Dispersive Spectroscopy and Electron Backscatter Diffraction detectors using the same software interface. The new WDS product platform includes the Lambda Plus and Lambda Super WDS spectrometers, covering up to 10 keV and beyond 15 keV energy ranges, respectively. Based on the sealed gas counter detector design, Lambda spectrometers are fully compatible with high vacuum applications that are especially important for SEMs with FEG emitters. The sealed gas detector design and extended energy range opens additional application domains for Lambda products, such as in situ and environmental WDS measurements.
