  • Wavelength: 190nm to 3200nm
  • Spectral bandwidth (slit width)
  • - 9 steps in ultraviolet/visible region; 0.1, 0.2, 0.5, 0.8, 1, 2, 3, 5, 7.5nm
  • -12 steps in near-infrared region; 0.4, 0.6, 0.8, 1.2, 2, 3, 4, 6, 8, 12, 20, 30nm
  • Resolution length range: 0.1nm
  • Wavelength scanning speed:
  • - FAST 1600nm/min (with 2nm sampling interval)
  • - FAST 700nm/min
  • - MIDDLE 200nm/min These are the speeds when scanning with 0.5nm sampling interval.
