With a focal length of 400 mm and a focal ratio of f/10, the ARYELLE 400 is the spectrally highest-resolution wide-range spectrometer in the ARraY echELLE series. The patented optical design consisting of echelle grating, prism, imaging optics and entrance slit can be customized for the wavelength range and high spectral resolution. Two-dimensional echelle spectra can be measured in the standard configuration with a slit width of 50 µm in the VUV range (175-330 nm) with a spectral resolution of up to 30,000 or up to 15,000 in the UV-VIS-NIR range (330-850 nm), depending on the wavelength range that can be detected simultaneously. Thanks to its optomechanical design, the ARYELLE 400 can be combined with a variety of different CCD and ICCD cameras. A mercury lamp and an internal shutter are used for automatic recalibration of the wavelength scale.

With the Sophi software supplied, all functions of the spectrometer-detector unit are controlled via an intuitive graphical user interface with an integrated script language for automated measurement sequences. Optionally, the operation can be extended by a LabVIEW library. Qualitative multi-element analyses are based on a spectral database evaluation of the detected spectrum. Algorithm-supported quantitative analysis requires calibration with reference materials.
