Abstract: A reflection meter for measuring the percentage of reflected light from a surface. A light source produces light which strikes the surface. The surface reflects the light into a chamber which directs the light to a detector. The detector senses the reflected light and produces a detect signal that represents the light reflected. A microprocessor receives the detect signal and calculates a percentage of light reflected from the surface which is shown on a display. An absorbing receiver engage the surface and absorbs any light that is transmitted through the surface.
