Aryelle Series Spectrometer

Aryelle wide range spectrographs

The Aryelle series of spectrometers from LTB are high resolution echelle spectrometers that can generate spectra of relatively arbitrary dimension with high wavelength stability, spectral resolution and radiation throughput.

The Aryelle spectrometers are used for highly resolving spectral measurement of plasma emission lines. The lines can be detected simultaneously within a large spectral wavelength range using a charge coupled device (CCD) or intensified CCD (ICCD) camera.

The Aryelle spectrometers available are the Aryelle150, Aryelle200 or Aryelle400.

The Aryelle150 is the most compact and cost efficient ultraviolet-visible-near infrared (UV-VIS-NIR) echelle spectrometer of LTB’s Aryelle series with a focal length of 150mm and 2kg weight without detector – suitable for reliable and portable laser induced breakdown spectroscopy (LIBS) and Raman applications.

The Aryelle200 is an inexpensive echelle spectrometer with fiber coupling for different CCD, electron multiplying CCD (EMCCD) and ICCD image detectors and has a focal length of 200mm and an aperture of f/10. Depending on the required simultaneously detectable wavelength range, it is possible to measure spectra from the ultraviolet (UV) up to the near infrared (NIR) with a spectral resolving power of 5,000 to 12,000 (at a slit width of 40µm).

The Aryelle400 model features 400mm focal length spectrographs and offer the customer vacuum ultraviolet (VUV) to UV sensitivity in the range 175-330nm, UV-VIS-NIR sensitivity in the range 330-850nm. The Aryelle-Butterfly has been developed for measuring wide range LIBS spectra and consists of two Aryelle400 spectrometers, the spectra of which illuminate one shared detector. The Aryelle-Butterfly is available with VUV-UV or UV-VIS-NIR sensitivity.

All Aryelle spectrometers come with Sophi controlling and evaluation software Sophi which controls all spectrometer and detector functions.
