Abstract
This paper focuses on the determination of cleanliness levels the contamination control plan and highlights of how the plan was implemented through the build and test of the CLAES instrument. The hardware development addressed both molecular and particulate contamination concerns however this paper will concentrate on particulate contamination because of its greater impact on CLAES performance. A primary noise source is off axis scatter from the earth surface. The stratospheric altitude of interest is 10 to 60 kilometers resulting in low altitude detetion of only 0. 2 degrees above the hard earth surface. This necessitated careful attention to straylight controls throughout the design fabrication assembly and ground test of the instrument. 2.
