Description
UV to mm optical constants of four Mg-rich glassy silicates (1-x)MgO-xSiO2, x=0.35, 0.40 and 0.50 (two samples), at 10, 100, 200 and 300 K. The optical constants are calculated from mass absorption coefficients measured in the 5 - 1000 µm (2000-10 cm-1) range and extrapolated in the range 0.024 - 5 µm and 1000 - 100000 µm.
