ABSTRACT:
A device for measuring the total reflectivity, i.e., specular plus scatter, f a small area of a material at various laser frequencies and intensities. The device includes appropriate transmitting and collecting optics in conjunction with a thermopile-type energy sensor with an external metering circuit. The metering circuit can be quickly adjusted to read total reflectivity of a sample placed in front of the reflectivity-measuring device.
