Near-infrared spectrometer IndiGo NIR

The near-infrared spectrometer IndiGo NIR has a modular design and can measure emssion, absorption and transmission spectra from 720 nm to 1040 nm at a resolution of about 2nm (FWHM). The IndiGo NIR can be connected to Smartphone or tablet via bluetooth or to a pc via USB-connection.
When connected via Bluetooth, the device operates autonomous on battery and can carry out measurements for up to 8 hours.
For data acquisition and analysis, a PC application for Win10 (USB-C connection) and an Android application (Bluetooth 5.0 connection) are available to the user.
The generated data are compatible with all chemometric software programs (R, Solo, Unscrambler, Quasar…). Likewise, firmware adaptation to existing chemometric models is possible.

Optional modules allow the analysis of liquid or solid samples.

Additional modules

  • NIR reflectance module for solid samples

    The NIR reflectance module adds a continuous near-infrared broadband light source (from 700nm to 1100nm) for reflectance measurements to the IndiGo. During operation, the electronics are protected by an integrated sapphire glass window.
    This spectrometer is suitable for protein, dry matter, fat and sugar measurements on food, wheat and flours.

  • NIR reflexion or transmission for liquid samples

    Thanks to a standard cuvette holder this module allows nir spectral measurements on liquids, pastes or micro beads. Depending on the configuration the module consists of a broadband nir-light source (from 700 nm to 1100 nm) for relfexion or transmission measurement.
