Abstract
A portable reflectometer is made using a diffuse light and light sensor cination to measure reflectivity of solar wavelengths. A cadmium sulfide photocell is used as the light sensor connected to a voltage divider network which provides a linear response to an internal light source. The light shield is placed around the light source and the light sensor to limit detected light to only that reflected on the surface due to the diffuse light source. The invention is mounted in a hand-held gun configuration to provide easy use.
