AST/ASTN series wavelength tunable light sources AST-XE series article

 AST-XE series   


  • Variable narrowband light output selection from UV (200nm) to Near IR (2.2µm)
  • Computer controlled via standard RS232 interface
  • Scans in both directions and in nanometers, Angstroms, microns, wave-numbers, or eV
  • May be configured for optimal fiber optic illumination
  • Modular design allows for reconfiguring

    ASTN-W series

  • Attenuation control
  • Couples to Spectral Products equipment
Simple, Flexible

Spectral Products has a tunable light source to meet your needs. Each model is based on our popular CM110 dual grating, 1/8-meter monochromator, paired with one of Spectral Products' broad b and light sources. When purchased together as a tunable


light source, you get pre-adjusted coupling and the best-matched grating(s) preloaded.
Depending on the requirements for better resolution/accuracy, other DK240 or DK480 monochromator can be coupled.



  • AST-XE series: ASB-XE-175, 175W Xenon light source based model
  • AST-W030/ASTN-W series: ASB-W030, 30W tungsten-halogen or ASBN-W high power  tungsten-

    ASTN-DX-W Series

    halogen light source based model.
  • ASTN-D series: ASBN-D130/ASBN-D230, 30W single or dual deuterium light source based model.
  • ASTN-Dx-W series: ASBN-Dx-W series, single or dual deuterium + high power tungsten-halogen hybrid light source based model.

Band-pass region and width is controlled by selection of monochromator slit size and gratings.
