Optics System
Procedures described in this section must be followed when servicing an optics chassis. All
of these points should be read and understood. Failure to do so may result in permanent
damage to the instrument:
All optical mirror surfaces are MgF
2
coated. Do not clean any of the components with water.
Do not attempt to clean the grating or prism.
Do not attempt to clean the camera surface.
Do not touch the surface of the optical components.
Do not attempt any alignment or calibration without the correct equipment and tools.
The Polychromator requires a transparent optical path. Do not use unauthorized lubricants or
glues that may out-gas.
Cover exposed optical components. Settling dust and airborne contaminants can degrade
performance.
Always allow adequate purge time for the polychromator before turning on the Peltier of the
detector.
This section provides procedures for access to and removal of field serviceable components
and assemblies of the optics system. Replacement procedures are the reverse, unless
otherwise stated.

Pre Optics System
The 5110 pre optics assembly cannot easily be removed from the instrument as it is factory
aligned to the RF box assembly. As such any components within the casting can be replaced
and realigned without removal of the complete casting assembly.
