DTMc300 Double Monochromator

  • DTMc300 double monochromator connectors
  • DTMc300 double monochromator entrance and exit slits
  • Compact configuration DTMc300 double monochromator

In each component monochromator, up to 3 diffraction gratings feature to permit measurements over a wide spectral range. Multiple configurations are achieved via the addition, at the entrance/ exit ports of each, of an additional slit with a computer-controlled selection mirror (SAM).

Delivering best uncertainty in detector responsivity and time resolved measurements, the DTMc300 may be arranged in the additive dispersion mode, applicable in solutions incorporating a UV component, and subtractive dispersion mode, sought by high level laboratories requiring unsurpassed accuracy and complete measurement confidence.

Core benefits






  • High configurational flexibility
  • Double monochromator comprising two TMc300 focal length monochromators
  • Czerny-Turner configuration, arranged for either additive or subtractive dispersion
  • Each single monochromator accommodates up to three diffraction gratings permitting single–scan measurement over wide spectral range (200nm-50µm)
  • Up to two entrance ports, one exit port on first monochromator (single mode) and one entrance port on the second monochromator (single mode)
  • Automated mirror-based port selection for use of multiple input/ output/ detector configurations
