ARCoptix OEM FT-IR module
Robust, compact and reliable OEM FT-IR module optimized for system integration

The ARCoptix OEM FT-IR module is the ideal product for system integrators (or labatoratories) looking for a customized FTIR measurement design. The OEM module exists in two configurations:

  • Fully integrated OEM module (OEM010) (as shown on picture) with integrated light source and detector.
  • Flexible OEM module (OEM011) with external detector module.
  • OEM010 module with integrated IR source and detector

    OEM011 module with integrated IR source and external detector module

    The ARCoptix OEM010 is our most compact FT-IR complete system. It features a built-in SiC globar heated to 1550 K and regulated in temperature to ensure stable illumination. The light that is being output by the instrument is first modulated by our permanently aligned interferometer, making it robust against stray light that might eventually reach the detector. The OEM010 rugged casing also holds a highly sensitive TE-MCT detector which maximizes the response of the system. Built from the same components, the OEM011 displays identical performances as the OEM010 while providing with an added degree of freedom thanks to its separate detector module.

    • All-in-one FT-IR or flexible confiuration
    • Compact and rugged
    • High resolution of 2 cm-1 (optionally up to 0.5 cm-1)
    • Easily connected to IR fiber systems
    • 3 possible TE-cooled MCT detector ranges:5000-1700cm-1 (2-6μm), 6700-1200cm-1 (1.5 - 8.5μm) or 5000-830 cm-1 (2-12μm)
    • USB connectivity
    • Cost effective
    How does it work?
    Permanentely aligned interferometer

    The heart of the FT-Rocket is dual corner-cube (retro-reflector) interferometer. The two corner-cubes are fixed to a common swinging arm, which rotates to create an optical path difference (with respect to the beam splitter) in the two arms of the interferometer.
    This type of design is called a permanently aligned interferometer. This particular arrangement of the interfeormeter is known to be the most robust against vibrations and temperature drifts. It never has to be realigned.
    The swinging arm of the interferometer rotates on wear-free flexure system, making this mechanical system extremely robust and durable.

    Solid-state reference laser

    For measuring the movement of the mirrors, a solid-state reference laser is coupled into the interferometer. Compared to classic HeNe lasers, the solid-state lasers that we use are more compact and have a much longer life-time. They have a very low temperature-induced wavelegnth drift and, when kept at constant temperature with a Peltier element, their wavelength can be stabilized to a few PPM, thus providing a very accurate and reproducible wavelength scale. This is crucial for ensuring a day-to-day and unit-to-unit consistency..

    Short-path, high pressure, high temperature flow cell

    A typical example of industrial application based on the OEM010 is shown here below. This customer driven configuration features a short path flow cell, designed to withstand high pressure (> 100 bar) fluids while placed in a high temperature environment. The modulated light emitted by the OEM010 is efficiently coupled to the cell thanks to a homemade accessory that enables a common-path configuration.

    ARCoptix Digital Acquisition Acquisition system: AoDAQ

    The AoDAQ is a multi-threading, cross-platform and versatile software that simultaneously takes care of:

    • (1) Handling communication with the FT-IR via USB
    • (2) Processing raw signals to deliver the spectrum
    • (3) Running a TCP ethernet server

    The AoDAQ can be installed on all sorts of computers, from desktop machines to embedded, low-power single board computers. Thanks to the hosting of a TCP server, the instrument data and parameters can be accessed locally and/or remotely. All communication with the instrument eventually reduces to a set of TCP/IP commands that allow to quickly acquire data, adjust parameters, monitor the instrument status etc. using the programming environment of your choice.

    Optical fibers

    ARCoptix offers two types of optical fibers for the mid-infrared:

  • Chalcogenide-IR (CIR) fibers transmit IR-radiation in the spectral range of 1-6μm (10000 - 6500cm-1). CIR fibers have an NA of 0.28 and are available with core diameters of 500 µm. These fibers ideally match the range of our spectrometers using 2-6 µm MCT detectors.
  • polycrystalline infrared (PIR) fibers transmit IR-radiation in the spectral range of 4-18μm. PIR fibers have an NA of 0.25 and are available with core diameters of 900 µm. These fibers ideally match the range of our spectrometers using 2-12 µm MCT detectors.

    Bk7/CaF2 fiber coupler/collimator

    Lens-based coupler provides a cost-effective solution for fiber coupling& collimation. Bk7 couplers are fine for the NIR range and up to 4 µm. CaF2 couplers are a good solution for the NIR and and MIR up to 8 microns. Standard fiber connectors are SMA-905, but FC/PC connectors or other types are available on request


    Reflective fiber coupler/collimator

    Reflective couplers/collimators are needed for the upper MIR range above 8 microns. These couplers use an off-axis parabolic mirror for optimal coupling performance throughout NIR & MIR. Standard fiber connectors are SMA-905, but FC/PC connectors or other types are available on request.
