Abstract
Optical apparatus which compares the transmittance of radiation through a coated product with the transmittance of radiation through only the base material of the coated product to measure the coating weight of the coating on the coated product. A dichroic filter or similar device is included to minimize or even eliminate radiation losses, due to reflections from the coated product, which affect the accuracy of the apparatus. The apparatus can be modified to measure selected characteristics of the base material instead of the coating.
