The refractive index information for Fraunhofer lines is accurate to four decimal places (for l> 2 mm: 2E-5). In wavelength ranges with limited transmission the accuracy ot the data is less. All information applies at room temperature and normal air pressure (0.10133 106 Pa).
Values listed on this page were taken from Schott's 1996 General Catalog. For more detailed information on these materials, please refer to the Schott optical glass catalog.
