ARYELLE 400 Butterfly spectrometer

The high-performance wide-range double echelle spectrograph provides two separate spectral setups for the VUV and UV-VIS-NIS ranges, each with 400 mm focal length and one shared detector – maximum flexibility for precise elemental analysis with LIBS and Raman spectroscopy.

  • Two separate spectral ranges: VUV and UV-VIS-NIR
  • High spectral resolution (9,000-50,000)
  • Large simultaneous wavelength range
  • Suitable with various detectors (CCD, ICCD)
  • High light throughput

Setup

The ARYELLE Butterfly is a unique double echelle spectrograph of the ARraY echELLE series. It combines two separate ARYELLE 400 spectrometers that sequentially illuminate one shared detector in a compact housing – a cost-efficient solution covering a wide spectral range with a very high spectral resolution. Thus provides the opportunity to measure with two-dimensional echelle spectra in the VUV and UV-VIS-NIR range with an enormous variability. Each spectrometer part of the ARYELLE Butterfly features an aperture of f/10 and a focal length of 400 mm. The dispersion unit with echelle grating, prism, imaging optics and entrance slit can individually be adapted to nearly all customer applications depending on the required simultaneously detectable wavelength range and spectral resolution. By exclusively applying a CaF2 prism and reflection optics with broad-band UV coatings, chromatic aberrations are avoided.
ARYELLE optical setup

Various CCD and ICCD cameras are suitable for the designed detection area of 27 x 27 mm². The light coupling into the ARYELLE Butterfly spectrometer is realized via SMA fiber for the UV-VIS-NIR range or via pure reflection transfer optics for the VUV range. 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.
