Double Monochromator - OB920/LifeSpec series

  • High throughput
  • Stray light rejection 1:1010
  • 100mm focal length
  • Seya-Namioka configuration
  • Kinematically mounted holographic grating
  • Temporal dispersion 2ps / 100nm
  • Spectral dispersion 8nm/mm
  • Computer controlled wavelength selection

To perform measurements of samples that exhibit a low quantum yield or for highly scattering biological samples or solids and powders that exhibit a high level of scattering, double grating additive monochromators are available, providing increased stray light rejection and the benefit of increased spectral resolution.

For requirements where ultra fast decay processes are being monitored and the contribution from the monochromator towards temporal dispersion of the fluorescence must to be eliminated, double grating subtractive monochromators can be supplied. A bifurcated fibre bundle accessory is available for remote sample excitation and sensing, or as a microscope attachment. The bifurcated bundle is mounted directly onto the sample chamber by means of a custom made assembly.
