The astronomical spectroscopy of the nineteenth century based on Brewster's angle has evolved through into the microwave and the modern optical lasers of today. David Brewster's important contributions to the knowledge of the polarization of light include the discovery that compression in one direction causes an isotropic solid to exhibit double refraction. He showed that complete polarization occurred (only one polarization was reflected) when the reflected and refracted rays were perpendicular, a phenomenon which occurs at what is now known as Brewster's angle. Wilhelm Karl Haidinger (1795-1871) after his education in Vienna, visited George Cuvier and J.-B. Biot in Paris and George Greenough, David Brewster and Thomas Allan in Edinburgh. In 1823 Haidinger moved to Edinburgh in order to arrange Allan's mineral collection. Under Brewster's influence Haidinger studied the absorption of light in crystals and he designed a simple and effective instrument named Haidinger's dichroscope. Observations on the connection between absorption and the direction of polarization of transmitted and reflected light led in 1848 to a well-founded theory bearing on Babinet's rule that a greater absorption of the whole spectrum of visible light corresponds to a higher index of refraction.
