Rp. Shukla et Dv. Udupa, Zygo interferometer for measuring refractive index of liquids and its application for heavy water analysis, OPT LASER T, 32(5), 2000, pp. 355-360
The Zygo interferometer for measuring refractive index of liquids such as h
eavy water is presented. The accuracy of measurement in the refractive inde
x of liquids is found to be +/-0.0002 in the Zygo interferometer. An applic
ation of Zygo interferometer for heavy water analysis is also presented. Th
e interferometer. is found to be useful for determining the percentage puri
ty of heavy water with an accuracy of +/-5% in the purity range of 0-100%.
