Spectrometer Basics
This chapter describes the major components of your Nicolet 4700
or Nicolet 6700 spectrometer, including the light source,
beamsplitter and detector. It then explains what you will need to
know before collecting data in various spectral ranges.
In the Spectrometer Tour (available through Getting Started) view
“From the front,” “The back panel” and “Inside the spectrometer”

external components.
