Our technology

Near-Infrared Spectroscopy (NIR) is a non-destructive analytical technique that uses light in the near-infrared region (typically wavelengths from 780 to 2500 nm) to analyze the chemical composition of materials. APOS uses other wave lengths spectrometer from within the group for other applications, e.g. for WoodClassifier.

APOS technology

Wood is a complex organic material composed mainly of cellulose, hemicellulose, lignin, and water—all of which strongly interact with NIR light.

  1. Light Interaction
    NIR light is directed onto a sample with APOS Sensor.
  2. Molecular Absorption
    Molecules in the sample absorb specific wavelengths of the NIR light, depending on their chemical bonds—especially O-H, C-H, and N-H bonds.
  3. Spectral Signature
    The NIR light that reflects off or transmits through the sample carries a spectral fingerprint unique to the material’s composition.
  4. Data Analysis
    Advanced algorithms interpret these patterns to quantify or identify properties with the APOS analytics software APC.
  5. Data Visualisation
    The ProcessOPT software then allows to visualize various parameters of various sensors in real time in parallel. ProcessOPT is deployed in various variations with different visualisations, depending on the application.

APOS Sensors

APOS offers various sensors for various applications, to measure in contact, distance or liquids. Those are IP65, ATEX 22 and can even work in pressurized environments of up to 25 bar and 200°C material temperature.

We continuously develop systems, applications, and calibrations for new solutions in other application areas. Contact us for any project/need.
