用稳频横向塞曼He-Ne激光器（STZL）在633 nm处测定了SnO含量为52-72 mol%的SnO-P_2 O_5（SP）透明玻璃的光弹常数。SP玻璃样品在950°C下在碳坩埚中熔融，并在1050°C下在氧化铝坩埚中熔融。熔融条件影响玻璃化转变温度和OH含量，但对PEC几乎没有影响。在-0.73 ~-1.98 × 10-12 Pa-1范围内，PEC随SnO浓度的增加而单调变化。
The photoelastic constants (PECs) of transparent SnO-P2O5 (SP) glasses with 52-72 mol% SnO were determined using a frequency stabilized transverse Zeeman He-Ne laser (STZL) at 633 nm. The SP glass samples were melted at 950°C in carbon crucibles and at 1050°C in alumina crucibles. The melting conditions affect the values of glass transition temperature and OH content but have almost no effect on PEC. The PEC varies monotonically with increasing SnO concentration from -0.73 to -1.98 × 10-12 Pa-1.
