When light passes through a substance, it decreases in velocity. 131 W. 22nd Street, Elmira, NY 14903 • Phone 607.733.7166 • Fax 607.732.5829 • quality@swiftglass.com © 2020 Swift Glass. Knowing the refractive index – among other thermal, chemical and physical properties – helps ensure that the glass material you’re considering for your application is suitable for its intended use. Much can be learned about the optical properties of a glass material by […] This is why light moves at its highest possible speed in a vacuum, where no electrons hamper its speed. With the help of a refractive index of glass, its density can be determined. It can also be used in estimating the thermophysical properties of hydrocarbons and petroleum mixtures. Your email address will not be published. Thus, the quality of glass is determined with the help of its refractive index. As it begins to travel through a material, the interaction between electrons and photons reduces the speed of light. For one thing, it can be used to calculate the focusing power of lenses and the dispersive power of prisms. When light passes through a substance, it decreases in velocity. 5 Things You Didn’t Know About Swift Glass, Pandemic Prompts Reshoring Trends for North American Manufacturers, Sight Glasses for Oil & Gas Industry Applications. This is manifested by an increase in the substance’s refractive index. Swift Glass offers assistance in craftsmanship, material selection, and manufacturing of custom solutions, and design, while guaranteeing high quality and precision.

Your email address will not be published. When this occurs, there is a change in the existing refractive index between the glass and the surrounding medium. Understanding the behavior of light can be an important factor when determining which glass materials to use for your manufacturing process. Also commonly referred to as the index of refraction, the refractive index, n, measures a ray of light as it travels from one medium to another. Snell’s law clarifies the relation between the angle of incidence and angle of refraction. As the density of the electrons increase, the velocity of light becomes slower. In addition, the amounts of transmitted and reflected light will determine not only the refractive index of a glass material, but also its angle of refraction. Understanding the behavior of light can be an important factor when determining which glass materials to use for your manufacturing process. Currently you have JavaScript disabled. This is because light gets transmitted and reflected as light rays pass through the surface of a glass material. There are also weaker dependencies on temperature, pressure/stress, etc., as well on precise material compositions (presence of dopants, … Many materials have a well-characterized refractive index, but these indexes depend strongly upon the frequency of light. Much can be learned about the optical properties of a glass material by looking at its refractive index. When Θi = 0°, the amount of reflected light can be determined using the following formula: Lastly, the intensity of light is reduced by an average of 4% due to lost reflection from the surface of most glass materials with a 1.5 refractive index.
