Only rarely was attention paid to the lighting system or lighting...Photonics HandbookLight-Emitting Diodes: A Primer: Light-emitting diodes (LEDs) are semiconductors that convert electrical energy into light energy. The color of the emitted light depends on the semiconductor material and composition, with LEDs generally classified into three wavelengths: ultraviolet, visible, and infrared.The wavelength range of commercially available LEDs with single-element output power of at least 5 mW is 275 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...Photonics HandbookColorimetry: How to Measure Color Differences: Colorimetry, the science of color measurement, is widely employed in commerce, industry and the laboratory to express color in numerical terms and to measure color differences between specimens. Applications include paints, inks, plastics, textiles and apparel, food and beverages, pharmaceuticals and cosmetics, displays, and other parts and products that reflect or transmit color.The use and importance of colorimetry has grown in unison with the increase of global manufacturing and processing. When plastic automotive trim produced on one continent must match a painted metal...Photonics HandbookIntegrating Spheres: Collecting and Uniformly Distributing Light: The integrating sphere is a simple, yet often misunderstood, device for measuring optical radiation.An integrating sphere’s function is to spatially integrate radiant flux (light).
