Determination of refractive index of silica glass for infrared wavelengths by IR spectroscopy

Measurements of radiation characteristics of fused quartz containing bubbles

“…Moreover, Tan [31] confirmed the validity of Equation (15) for wavelengths up to 6.7 µm. Therefore, due to its wide range of validity (from 0.21 to 6.7 µm) at room temperature, Equation (15) is used in the present study.…”

Optical constants of silica glass from extreme ultraviolet to far infrared at near room temperature

“…In the spectral region from 0.2 to 7 µm, the absorption index of silica glass is very small and may be assumed to be zero for all practical purposes as suggested by Figure 1. Moreover, reported data, including that of Popova et al, 49 indicates that the refractive index is satisfactorily predicted by the Sellmeier formula reported by Maliston 16,23 between 0.2 and 7 µm and given by Equation (20).…”

“…and (iii) n η and k η are computed using Equation (16). The advantage of this procedure is that (a) fitting the reflectivity is easier than fitting n λ and k λ independently, (b) both n λ and k λ can be derived from a single curve fitting, and (c) the result automatically satisfies the Kramers-Krönig relations.…”

Water diffusion in silica film during silicon wet oxidation

“…By eliminating m from Eqs. (11) and (12) and replacing k with the corresponding wavenumber, k = 1/k, one can obtain…”
