OPTICAL SPECIFICATION Sample Clauses

OPTICAL SPECIFICATION. Note 1 Refer to Figure 1. Make scans at the center of the web and (plus/minus) 100 mm from the center of the web for each QC sample pulled from a finished roll. Make all scans on the ▇▇▇▇▇▇ ▇▇▇▇▇ Lambda 9 spectrophotometer equipped with an integrating sphere. Scans are to span the wavelength region between 400nm and 820 nm, with measurement every 5nm. Base all chromaticity measurements on color illuminant D65 (CIE 1931). Note 2 All reflection measurements are to be specular and made at near normal incidence. Laminate samples (coated side out) to a specially designed light trap (this is a laminate made up of .090" clear float glass, approximately 11 mm (.450") of Monsanto's black PVB and a piece of 1/8" bronze glass) using Norland type 7204 U.V. curing adhesive. Note 3 Smooth interference fringes set up by the index mis-match between the PET and hard coat using a simplified least squares procedure (from Savitzky, A. and ▇.▇. ▇▇▇▇▇: Analytical Chemistry vol. 36 no. 8, pp 1627-1639). Note 4 Determine the coating absorption using non-laminated samples. Measure coating absorption at the center of the web only for each QC sample pulled from a finished roll.
