Optical Properties
The optical dispersion of fused silica can be approximated by the following Sellmeier equation:
where the wavelength is measured in micrometers. This equation is valid between 0.21 and 3.71 micrometers and at 20 °C. Its validity was confirmed for wavelengths up to 6.7 m. Experimental data for the real (refractive index) and imaginary (absorption index) parts of the complex refractive index of fused quartz reported in the literature over the spectral range from 30 nm to 1000 m has been reviewed by Kitamura et al. and are available online.

Famous quotes containing the words optical and/or properties:
“It is said that a carpenter building a summer hotel here ... declared that one very clear day he picked out a ship coming into Portland Harbor and could distinctly see that its cargo was West Indian rum. A county historian avers that it was probably an optical delusion, the result of looking so often through a glass in common use in those days.”

“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
