text: The essential components of a spectroradiometric system are as follows:
  *Input optics that gather the electromagnetic radiation from the source (Diffusers, Lenses, Fiber optic light guides)
  *An entrance slit, determines how much light will enter the spectrometer. A smaller slit with have greater resolution, but less overall sensitivity
  *Order sorting filters for reduction of second-order effects
  *Collimator directs the light to the Grating or prism
  *A grating or prism for dispersion of the light
  *Focusing optics to align the light onto the Detector
  *A detector, CMOS sensor or CCD array
  *A control and logging system to define data and store it.
