TABLE NOTES
  1. The Zfine values listed above in computer units apply at the optical axis for the default instrument Zfine value of 4.10 entered into the CS-100.
  2. The free spectral range (FSR) and FWHM in Z-space at ~6600 Å are 700 and 25, respectively. These values do not depend on plate spacing. The former is accurate to 1% or better. The latter is for an optimized parallelism; values for individual setups may be higher by ~10-20% because of the precision limits of the parallelization procedure. Accordingly, the FWHM in wavelength space is only reproducible at the 10-20% level.
  3. Fractional orders are caused by small phase shifts due to the reflective coating on the etalon mirrors.
