Abstract

A photometer system is provided. The photometer system includes an optical filter having a narrow stopband. The optical filter is positioned to receive a combination of narrowband light and infrared light, wherein the infrared light is radiated from an article illuminated by the narrowband light. The bandwidth of the stopband overlaps a bandwidth of the narrowband light. The system includes an infrared detector positioned to receive filtered light from the optical filter with the narrowband light reduced by the optical filter. The infrared detector is operative to detect the infrared light radiated from the article as passed by the optical filter.
