“…Lead oxide, PbO, is remarkable in that the addition of PbO reduces the birefringence all the way to zero and then to negative values at high content . As noted, zero-stress optic compositions are of particular technological interest, but only a few additives are known to confer this behavior, in particular PbO, and also Bi 2 O 3 and TI 2 O. , All are heavy, expensive, and difficult to recycle and/or highly toxic. It is of considerable interest to understand the compositional dependence of the birefringence and to identify replacements with more benign environmental impact.…”

By comparing data on a variety of examples, an empirical correlation for the photoelastic response of simple metal oxides is discovered and used to predict new families of zero-stress optic glasses. The birefringence induced by uniaxial stress on glass is found to correlate well with the ratio of the metal oxygen bond metallicity to the metal coordination number; the metallicity itself is quantified through the metal oxygen bond length. This correlation was obtained by consideration of the stress optic response of a number of oxide crystals, obtained both from the literature when possible and also from first principles calculations. The correlation obtained provides a simple rule for choosing the composition of oxide glass so as to minimize the stress optic response; this rule is shown to agree with known data on lead oxide glasses and to predict the existence of previously unknown lead-free, zero-stress optic glasses. These glasses were then synthesized, tested, and shown to give the predicted response.

“…Of particular technological interest are zero stress-optic glasses, in which, as the name implies, the coefficient vanishes. It is well-known that glasses with high lead oxide content may have zero and even negative stress-optic response [1]; this behavior can also be induced by thallium oxide and bismuth oxide [2][3][4][5].…”

“…Zero stress‐optic glasses are of interest technologically in image reproduction systems, where it is critical to maintain image fidelity under unpredictable and asymmetric environmental factors. Before 2007, only a handful of other glass composition with similar photoelastic response to the lead silicates had been found, 2 and none of these glasses exhibits the same variety of excellent properties as the Pockels glass, for example transparency, high index of refraction, high transmission, low cost of production, and so forth. Although a theory of the stress‐optic response was formulated by Mueller, 3,4 it is not predictive and so it has not been easy to design new zero stress‐optic compositions.…”

Recently an empirical model was established to predict the photoelastic response of a glass based on its composition and the crystalline structure of its constituents. In the present work the model was tested in detail by comparing the local structure assessed by a combination of nuclear magnetic resonance and Mössbauer spectroscopy with the model predictions and the measured photoelastic response. The system investigated was (SnO) x (P 2 O 5 ) 1Àx . It was found that while the original simple model based on data on the pure components predicted the composition of the zero stress-optic glass to within about 15 mol%, inclusion of data on mixed systems, more reflective of the true glass structure, gave substantial improvement of the prediction. This finding further confirms the relation of local bonding structure to the photoelastic response of glass.
