 Crossed C-T Mode

  • High efficient plane holographic grating
  • Optical parts with SiO2 overcoating
  • Sealed monochromator
  • Autoswitch of light
  • SourceStray light: 0.03%T

Automatic Six-position Cell Holder

  • Spacious sample compartment can hold up to a 100mm cell
  • Various types of cell holders can be selected for different applications
  • Auto- rotary six-position cell holder, shortens the sample exchange time
  • Entrance port and exit ports of the light beam in the sample chamber are protected by quartz window, to prevent the optical system from contamination.
