The ARYELLE 200 is a spectrally high-resolution, fibre-coupled spectrometer from the ARraY echELLE series. It also offers high sensitivity and image quality within an affordable, compact framework. Constructed with a focal length of 200 mm and a focal ratio of f/10, the system provides an adaptable optical platform for quantitative and qualitative spectral analysis. Depending on the intended application, the primary dispersion unit, comprising an echelle grating, cross-dispersing prism, imaging optics, and entrance slit, can be tailored to specific spectral ranges and resolution requirements.

Engineered without moving parts, the ARYELLE 200 features a rigid casing designed to maintain alignment and performance over time. Its patented optical arrangement relies entirely on high performance reflective optics, only exception is the prism used to separate the echelle grating orders, in order to minimise transmission losses across the entire spectral span from the ultraviolet (UV) to the near-infrared (NIR).

Depending on the simultaneously detectable wavelength band, two-dimensional echelle spectra are captured with a spectral resolution ranging from 7,000 to 15,000 using a 40 µm slit width. Designed around standard 1/2 inch sensors with 13 x 13 mm² detector area, the ARYELLE works with a wide variety of camera systems, including CMOS, CCD, EMCCD, and ICCD detectors. An internal optical shutter and an integrated calibration lamp facilitate automatic wavelength scale recalibration directly within the system.

The combination of a small physical footprint and high optical throughput makes the ARYELLE 200 suitable for both laboratory applications and industrial process monitoring. It is commonly deployed in elemental and material analysis using laser-induced breakdown spectroscopy (LIBS), Raman spectroscopy but also other optical spectroscopic methods. Its durable and compact build allows straightforward transport between different testing sites, making it practical for mobile or multi-site measurement routines. Standard system offers combine the high-resolution ARYELLE 200 spectrometer with a CMOS or an ICCD detector package.

Software of Aryelle 200

Control over all spectrometer and detector functions is managed by the supplied Sophi software suite, which features an intuitive graphical user interface along with an integrated module for automated measurement sequences. Sophi processes raw optical data, mapping lines against an integrated spectral database of approximately 50,000 lines based on the NIST “Strong Lines” database. Detected lines are automatically identified and assigned to their corresponding chemical elements, and the library can be edited or expanded by the operator as needed.

Qualitative multi-element identification is supported directly, whereas algorithm-driven quantitative analysis is performed using certified reference standards. Routine maintenance is simplified via an auto-calibration function that uses the internal calibration lamp to update the wavelength scale automatically. Collected spectra can be exported into standard file formats. For custom system integration, the optional SophiServer software grant complete programmatic access to all spectrometer operations, reducing development effort through included sample code.
