SPECORD 200 PLUS UV/Vis spectrophotometer

SPECORD PLUS series UV-VIS spectrophotometers DOUBLE-BEAM SPECTROPHOTOMETERS

Real double-beam spectrophotometer with monochromator slit width 1.4 nm, dual thermally stabilized CDD detector and control via PC.

Main advantages:

  • monochromator with concave holographic grating and reduced stray light;
  • minimal quantity of moving parts in the optical system ensures reproducibility, vastly improved signal-to-noise ratio and high concentration of radiation energy;
  • aspheric optics for optimized, precise spectral imaging;
  • pre-adjusted and voltage stabilized radiation sources;
  • Integrated holmium filter for automatic wavelength calibration, for precision and reproducibility of wavelength setting;
  • maximum lamp service life;
  • double-beam design of the optical system to ensure high accuracy of results – simultaneous measurement of the working and reference signals;
  • ability to vary the wavelength resolution value enables to view all the spectral features;
  • position of the second cell right in front of the detector permits analyzing turbid samples.
