Abstract : Transmission and relative resolution measurements were made before cleaning, and transmission, schlieren, relative resolution, and interferometric measurements were made after cleaning, on the right-hand and left-hand windows of Gemini spacecraft G-IV to G-VII. Chemical analyses of the contamination cleaned from the windows show that the primary constituent is amorphous silica.
