There will be no finger prints on the optical surfaces. The parts must be free of any air bubbles. Optical surfaces will be free of scratches. Scratches will be identified by holding the part at 10”, reflecting overhead lighting off of the part so that the part appears white. Any scratches, if visible, will appear black. 3.1.3 Material Handling Always wear clean, lint proof gloves while handling the parts. Remove the parts from the packaging very carefully. Do not place or drag the parts on any surface which can cause scratches. SECTION 4.0: FABRICATED COMPONENTS 4.1 Machined, Cast, or Molded Metal Parts Following are the standards used for machined, cast, or molded metal parts. Scratch and Dig: MIL-O-13830A Surface Roughness and Waviness: ANSI Std. B46.1-1985 Finished coatings: Per drawing specifications. Unless otherwise specified the Surface Roughness and Waviness is to be 32 micro inches or better as per ANSI std. B46.1-1985. Unless otherwise specified break all sharp edges to R.03. Unless otherwise specified inside corner radius machined to R.005.
