DuoVista is a state-of-the-art system of two monochromators, providing a wide spectral range, excellent imaging quality (DM55 and DM77) and a large number of possible grating sets that allow a working range from 180 nm to 75 µm with a spectral resolution of several tens of picometers thanks to the use of double scattering. The gratings are placed on a software-controlled carousel (3 positions), where the position of each grating can be controlled and optimized separately for maximum quality of the resulting spectra. The DuoVista system is usually equipped with excellent tunable bandpass filters, suitable for the highest efficiency and perfect suppression of scattered light (stray light rejection). With the ability to build custom instruments, this makes S+I spectrometers an elegant tool for all possible Raman spectroscopy and microscopy applications (including AdFoCon adaptive automatic focus control).

DuoVista comes in three different versions:

  • DM33i: base level bandpass filter for medium to high resolution and good stray light rejection
  • DM55i: a top bandpass filter solution with excellent quality monochromators
  • DM77i: the best technology and technical processing of the combination of two monochromators with an ultra-high-end bandpass filter, extremely high resolution and suppression of stray light
