Optical constants of amorpous SiO₂ and GeO₂ in the region of valence band.
Optika Spektrosc., v. 29, pp. 66 - 70.

Optical constants:

Some details:
As the opitical properties of quartz glasses are known to depend on the prehistory of samples, the processing of 5 different samples was made in two ways (rough one usual in the optical industry and that with additional polishing by Ar ions).
The optical constants were determined by 4 methods: (i) Measurements of reflectivity of polarized radiation incident at 3 different angles following by solution of the Fresnel equations; (ii) Measurements of trasmittance (for tablettes of ultra-fine powder); (iii) A combined method applied to both kind of the data following by solution of Fresnel equation for the normal incidence; (iv) Kramers-Kronig method.
