摘要

Fictive temperature dependence of refractive index, density, and Raman spectra of commercial dense crown optical glass widely used for lens production is investigated. It is found that the main peak in Raman spectra shifts higher with increasing the fictive temperature. As well as density and refractive index, this peak position has linear relationship with the fictive temperature. Relaxation of Raman spectra is similar with that of refractive index, and they are different from that of density. For the comparison, one commercial soda-lime-silicate glass is investigated as well as dense crown optical glass. Raman spectrum of this glass shifts lower as the fictive temperature. The difference between each relaxation time is less than that of dense crown optical glass.
