Data is presented which details investigations of substrate throughprint in low scatter nickel plated aluminum mirrors. Effects of fabrication procedures are examined. A novel method is described for photographically recording the visible light scattering of mirror surfaces at near specular angles. Application of the technique to quantitative scatter measurement is considered. Use of the test for inprocess inspection is described.
