title: Internal total reflection in monoaxial crystals.
abstract: Formulas to determine the limit angle of the total internal reflection in monoaxial birefringent crystals can be obtained. With these formulas the curves limiting the field of a Nicol prism were calculated; there is good agreement between calculated and experimental curves.
