The index of refraction for D2O at common wavelengths was measured for several temperatures at atmospheric pressure. While heavy water fs refractive index was precisely measured decades ago using the transition lines of elements, those wavelengths are seldom used now that inexpensive lasers provide a range of available wavelengths. We review those measurements, note some inconsistencies between research groups, and fit the best of the literature data to a simple equation that allows an easy calculation for the refractive index of D2O at any visible wavelength and between 5 and 95 C. We then compare to our measured refractive index values for three He ]Ne laser wavelengths (543.5, 594.1, and 632.8 nm) over a temperature range from 15 to 65C and find good agreement.
