IROS 05 Series FTIR Spectrometers

IROS 05 FTIR spectrometer is designed to provide the wide range of sample measurement techniques in the most challenging environments from the laboratory to the pilot plant. Compact size, reasonable price for unique set of accessories and high performance – these advantages of IROS 05 Spectrometer allow it to fit to most of research and field tasks as a mid-level spectrometer for academic and industrial applications.

Mean Features:

  • Wide array of functions due to various attached modules and detectors.
  • Capability of additional external devices connection for IR spectrum registration.
  • Stability to temperature fluctuation and vibration due to unique patented interferometer design.
  • Moisture durability because of ZnSe optics
  • Compact and light-weight.

IROS 01 FTIR spectrometer

IROS FTIR spectrometers have a unique “double cat’s eye” interferometer patented 1993.

Advantages over classical Michelson interferometer:

  • Resistance to misalignment. There is no need to compensate thermal drifts and vibrations misalignments
  • High beamsplitter resolution
  • The angle of incidence for beam splitter is 90°. It allows avoiding polarization effects, angle of incidence for Michelson
    interferometers are 45° or 30°  

Wide range of optional modules
