A measurement method is described to select the best orientation of an anti-reflective panel with respect to a CRT screen before bonding. Reflection measurements are made at the center and at each corner. Anti-reflective panels are sorted to select those where specular reflections are minimized at the center and top half, and to reject unsuitable panels. The same measurement technique may be employed with CRT screens having anti-reflective layers applied directly to the screen by selecting the best orientation before gun and neck hardware are fixed. This article discloses how specular reflections can be minimized over the most important part of a CRT screen, when using a multilayer thin-film type of anti-reflective (A/R) coating.
