he specimens were made of Titanium 6Al-4V foil, .005 inches in thickness, and TIODIZED with Type I and Type II. The ULTRA V-E17, when used, was TIODIZE® black organic coating. The absorptance was determined by the 19 point integration between 0.32 and 2.1 microns wavelength. The emittance was arrived at by a 25 point integration between 4.8 and 26.2 microns. Spectral measurements were made in either a heated Hohlraum chamber or a Gierdunkle integrating sphere with an incident angle of 20 degrees on specimens water cooled to approximately room temperature.
