本文提出1～15微米波段、93～238K 温度时 Irtran 2(热压微晶 ZnS)折射率的数据,其数值范围从高温和短波时的2.35到低温和长波时的2.12,对所有波长,当温度为104K 时,dn/dT 的平均值约为4×10~(-5)K~(-1),而 dn/dT 的温度变化率为2×10~(-7)K~(-2)。
This paper presents the data for the refractive index of Irtran 2 (hot pressed microcrystalline ZnS) in the 1-15 micron band at 93-238 K. The values range from 2.35 for high temperature and shortwave to 2.12 for low and longwave, and for all wavelengths, when The average value of dn / dT is about 4 × 10 ~ (-5) K ~ (-1) at 104K and the temperature change rate of dn / dT is 2 × 10 ~ (-7) K ~ (-2) ).
