Summary
The reflectance spectra of ruthenium were measured from 400 to 700 nm in air and in oil with polarized light for the ordinary and the extraordinary ray. The character of the bireflectance changes at about 500 nm from negative (at shorter wave lengths) to positive. Absorption coefficients, indices of refraction and absorption indices were calculated, compared to literature values and related to the HCP structure of ruthenium.
Zusammenfassung
Die Reflexionsspektren von Ruthenium wurden von 400 bis 700 nm mit polarisiertem Licht in Luft und in Öl für den ordentlichen und den außerordentlichen Strahl gemessen. Der Charakter der Bireflexion wechselt bei ca. 500 nm von negativ (bei kürzeren Wellenlängen) nach positiv. Die Absorptionskoeffizienten, Brechungsindizes und Absorptionskonstanten wurden berechnet, mit Literaturwerten verglichen und mit der HCP-Struktur von Ruthenium in Bezichung gesetzt.
