Question/Comment: 

Not clear if provision to make routine internal focus adjustments
inside NIC-FPS regarding the mode change, filter change, temperature
change...


Submitted by: Bruce Gillespie


NIC-FPS Response:

Since the etalon and filters are in collimated beam space, we expect no
change in focus when changing these.  The optical design is confocal at
all operating wavelengths.

A tolerance analysis is require to determine whether an internal
focusing mechanism is necessary, and on what what optical element (i.e.
collimator, camera or FPA).

To date, we see no need for an internal focusing mechanism.
