1854Pereira Polarized Light (ed. 2) 50 There is no essential difference between the two parts,..and either part..may be used as polarizer or analyzer; but whichever we use as the polarizer, the other then becomes the analyser. Ibid. 132 On rotating the film (the analyzer and polarizer remaining still), a brilliant colour is perceived at every quadrant of a circle, but in intermediate positions it vanishes altogether..so that when the film alone is revolved one colour only is seen, but when the analyzer alone is revolved, two colours are seen. 1863[see analyser 3]. 1879Rutley Stud. Rocks vii. 48 The polariser should revolve with perfect freedom. |
