1968 Chem. Abstr. 69 6626/2 A goniometric study of crystals is rarely made because labs. often have no goniometer. The goniometric method in many cases can be replaced by photogoniometry.

1998 Thin Solid Films 313–14 68 This set up is applied to the study of transparent materials such as Ion Beam Sputtering..of thin SiO₂ layers deposited on silica glass substrates... Ellipsometric results are in very good agreement with those obtained by photogoniometry.
