ARYELLE 400

The flagship of ARYELLE echelle spectrometer series with very high spectral resolution in the VUV or UV-VIS-NIR wide-range with 400 mm focal length – for precise elemental analysis with LIBS and Raman spectroscopy.

Highly sensitive with high wavelength stability
High spectral resolution (9,000-50,000)
Large simultaneous wavelength range
Suitable with various detectors (CCD, ICCD)
High light throughput

Setup

The ARYELLE 400 with a focal length of 400 mm and an aperture of f/10 features the highest spectral resolution of the wide-range spectrometer ARraY echELLE series. The patented optical setup with echelle grating, prism, imaging optics and entrance slit can individually be adapted to different customer applications. Depending on the required simultaneously detectable wavelength range, the ARYELLE 400 provides the measurement of two-dimensional echelle spectra. At standard spectrometer configuration with 50 µm entrance slit, a spectral resolving power of up to 30,000 for the VUV range (175-330 nm) or up to 15,000 for the UV-VIS-NIR range (330-850 nm) can be achieved. The optomechanical setup is designed to fit various CCD and ICCD cameras. Automatic recalibration of the wavelength scale is provided by a mercury lamp and an internal shutter.

The supplied operating software Sophi with optional LabVIEW library allows fully control of all spectrometer-detector functions via graphic user interface and provides automated measurement routines with an integrated scripting language. All lines of the gained spectrum are automatically analyzed with the integrated atomic spectra data base and qualitatively assigned to the corresponding elements. Quantitative analysis is based on calibration with reference materials.
