Chromaticity Basics: Factors, Calculation, and Application

Chromaticity Basics, Calculations, Factors, and Applications

Color is a universal language. At traffic lights around the world, drivers understand to stop on red and go on green. For many signaling applications, including those in the railroad and aerospace industry, operators are trained to recognize and respond to very specific colors. So how do you make sure that your light fixture outputs…

Mechanical Properties of Glass: Design to Survive Stress, Impact, and Abrasion

Mechanical Properties of Glass

When designing a lens for a harsh environment, you need to choose a material that is resistant to pressure, abrasion, and impact. Some applications, such as exterior aircraft lighting, can push a material to its limits. Exterior aircraft lenses are exposed to smog, dust, and other air pollutants at very high speeds; the resulting impacts…
