Über ein graphisches Verfahren zur polarisationsoptischen Bestimmung von Dicke und Brechungsindex beliebig dicker, nichtabsorbierender, homogener Schichten auf Glas

Abstract

Vašiček's universal method for determining the optical constants of nonabsorbing, homogeneous layers of any thickness on glass has been limited to the special case of ligth incidence under the polarizing angle of the glass carrier. This enables one to base the measurements on a reference glass carrier of well known refractive index, and simplifies the relationship of the variables. After calculating all parameters and computing some normalizing curves for this particular reference carrier, it is possible, to evaluate graphically all polarimetric measurements for any kind of glass carrier or wavelength and for all data of the layers as thickness or refractive index. The feasibility of the normalizing process has been proved.
