Abstract
A novel fixed block polarized, specular reflective accessory apparatus and method are disclosed, including providing an infrared light generator, a polarizer to polarize infrared light generated by the infrared light generator, a fixed block having an aperture for receiving a sample, a first fixed position mirror on one side of the fixed block wherein the first fixed position mirror is positioned to receive incident infrared light parallel to the plane of reflection at a fixedly set angle, and a second fixed position mirror positioned to receive infrared light reflected from said sample. In one aspect, the fixedly set angle preferably is fixed at about 55.degree.. The novel fixed block polarized, specular reflective accessory apparatus and method provide a high efficiency, high accuracy, high quality and quantitative process control coating measurements for coating operations in manufacturing coated aluminum alloy sheet.
