TY - JOUR AU - Subotowicz, M AB - The optical apparatus described permits the measurement of the reflection coefficient R of an investigated sample at incident angles in the range from 8 to 90 degrees . The system is constructed from four plane mirrors and a spherical one. The light path in the apparatus is relatively compact. With aluminium mirrors the transmission of the apparatus is approximately 80%.
