It is clear you sent us a simulation. Foreal can shift the CWL a little longer, say 10-15nm.  Please comment on the following:

  1. What do the real data plots look like from your current coating vendor?
  2. Do you really need the exact CWLs at the 4 angles?
  3. What is the CWL tolerance (in nm) for the 4 CWLs?
  4. What is the FWHM tolerance (in nm) for the 4 CWLs?
