Abstract: A light probe for use with a photometer includes a silicon photo-voltaic sensor mounted behind a specially designed lens which accurately corrects the sensor to a cosine distribution curve. A light-blocking eyebrow is disposed around the lens to control the light relative to the lens surface. The measured light distribution as detected by the sensor is a function of the curvature, diffusion factor, and surface roughness of the lens, and the relationship of the eyebrow to the lens.
