Abstract

Figures 14 and 15, and Table 1, give the optical constants of tin found from formulas (II.9), allowing for the dependence of the surface impedance on the angle of incidence of the light. The maximum value of the correction term was about 1% in the range λ = 0.7–1 μ, 0.3% in the range λ = 2 μ, and negligible in the range λ > 2 μ. The results given constitute the averages of many sets of measurements. Figures 14 and 15 give the total dependence of n and ϰ on λ, and also the short-wave region, shown separately. Measurements of the optical constants were carried out at three temperatures, 293, 78, and 4.2°K. The temperature dependence of n is considerable over the whole spectral range; the temperature dependence of ϰ is only large in the range λ = 8–12 μ. In the range λ = 2–5 μ, ϰ varies only slightly with temperature.
