Measurements of light based only on physical properties are of limited use to the lighting designer. Instead, the tools to measure and communicate the characteristics of light sources and illumination consider the impact of the physical attributes of light on the human visual system. This unit covers the photometric measures related to the quantity of light and illumination and the colorimetric systems used to characterise the colour of lights and objects. The calculation methods underlying these measures are included, with an emphasis on useful simulation techniques. The derivations, meanings, proper applications, and limitations of these measurements systems are discussed. An overview of physical instruments for photometric and colorimetric measurements is included. Students learn to apply knowledge of photometry and colorimetry to evaluate lighting products.
