Abstract:

The Tunable Laser Spectrometer (TLS) are sensitive to optical standing wave contamination that can be ameliorated by making small adjustments in instrument alignment after system integration. However, the Mars Science Laboratory (MSL) TLS optical components had been staked prior to Integration and Test (I&T) and could not safely be realigned. For all precision assemblies subject to correction by mechanical adjustments, provide a design capability that allows adjustments for key mechanical parameters both before and after integration. Do not permanently fasten assembly components until it is demonstrated that functionality and performance requirements can be met with adequate margin during I&T.
