ABSTRACT:
A colorimeter for characterizing the color of an object is placed in an environmentally sealed enclosure for use in industrial environments. In order to maintain an acceptable operating temperature for the colorimeter's electronics and lamp, a heat shield is placed around the lamp to substantially isolate it from the electronics. The heat shield and the environmentally sealed enclosure are made of a highly heat conductive material such as aluminum. The heat shield is thermally coupled to the environmentally sealed enclosure.
