IROS P03 is a research spectrometer for mid-IR spectrum analysis with spectral resolution of 0.12 cm-1. Its operating spectral range can be spread. Maximum sensitivity is reached using changeable detectors and IR radiation sources for operating spectral ranges.
There are 2 optical ports: input for radiation injection from external source, output while working with special equipment and detectors.

Radiometric unit is mounted at the input optical port and is used for external radiation source spectrum registration:
  • Air pollution track monitoring method, remote sensing (passive/active mode)
  • Toxic gases and vapours detection and identification
  • Research
  • Technology process parameters and product quality control in photonics, optics, light engineering
  • Special-purpose machinery products design and test

IROS P11 FTIR spectrometer is perfect for near-IR spectrum analysis


The IR Fourier spectrometer IROS P11 is designed for quantitative and qualitative spectral NIR analysis

Main advantages:


  • high data informative value
  • high measuring speed and accuracy
  • sample preliminary preparation is not required
  • special personnel training is not required

IR absorption spectrum bands location and bands intensity give sample qualitative and quantitative (i.e. concentration and other properties) composition information respectively.
The calibration model of the relationship between absorption (transmission) index and component concentration (sample property) is preliminarily calculated using calibration tests for samples with well-known spectra, component concentrations, and other properties.

The main part of the IROS P11 spectrometer is the Michelson-type interferometer with self-compensation and without the need for dynamic alignment.

The IR Fourier spectrometer IROS P11 uses NIR spectroscopy and chemometric system of results processing combination. This method is much-needed for such fields of the industry as food production, drug manufacturing, perfumes, and cosmetics production. Easy to use and high-speed analysis and results objectivity make this mode essential for raw materials input quality control, manufacturing process critical points control and end-product properties control. The method is recommended, in particular, for counterfeit drug detection.

Changeable detectors are used: InGaAs for a spectral range of 4 000 - 9 000 cm-1 and Si for a spectral range of 8 500 - 12 500 cm-1.

IROS P11 is used for pharmaceutical, chemical, polymer, textile, food, and compound animal feed industries product identification and quantity analysis.
