光学材料のn・l積の温度依存性の測定

抄録

In view of the fact that the temperature dependence of n·l product (equal to the real optical path length) of the optical materials are very important for designing optical devices, here we report the measured results for many optical materials, e. g., LiNbO₃, LiTaO₃, YAG (Nd), opto-ceramics, etc. We measured them by Haidinger's fringe count method over the practical temperature range of 20°C-120°C.
