Multi-purpose ATR/SDR module


The module is designed to measure the spectra of microobjects by the method of attenuated total reflection (ATR) with simultaneous visualization on the built-in and external monitor, as well as by the method of specular-diffuse reflection (SDR) with a drop angle of 45° at the upper location of the sample.

Main advantages

  • Preliminary sample preparation is not needed for most cases

  • Built-in video camera allows to register spectrum and observe sample (with video capturing) simultaneously


  • Spectra registration both in ATR mode and in specular/diffuse reflection mode


  • Diamond, ZnSe, and Ge prisms. Quick ATR prism replacing by the operator


  • Quick operating mode changing


  • Sample types: liquids of any viscosity grade (solutions, suspensions, oils), powders, polymer films, fibers, solid and elastic samples up to 0.25 mm2 (paint and varnish coatings fragments, polymer particles)
