STATEMENT OF WORK

1.0 Introduction/Background:

The Aerosol Wind Profiler (AWP) project integrates two beam expanding telescopes in the instrument package. A prototype Engineering Development Unit (EDU) is being converted into a fully functional expander of identical specification as the two currently integrated expanders. Welch Mechanical Designs (WMD) fabricated the main off-axis mirrors for the two current expanders. This procurement is for WMD to fabricate and coat an additional set of off-axis mirrors for the AWP project.

2.0 Scope of Work:

• Manufacture M1 mirror (quantity 1), as specified in drawing MRa-NASAxBE-03- CLEAN JM.pdf (attached)

• Manufacture M2 mirror (quantity 1), as specified in drawing MRb-NASAxBE-03- CLEAN JM.pdf (attached)

• Apply protected gold optical coatings to both mirrors above.

Other Considerations:
