Abstract

PURPOSE:To permit the photometry unit of a double beam spectrophotometer having a simpler constitution to reduce the measuring error by providing means to allow the real images of a sample and a contrast sample by a converging spherical mirror to be focused with equal magnification on the photoactive face of a photoelectric detector. CONSTITUTION:The luminous flux having penetrated through a sample 1 is reflected by, e.g., a plane mirror 8, before being applied to an edge mirror 3 so that the optical path between the sample 1 and a converging spherical mirror 5 is made adjustable by the positions of the plane mirror 8 and the edge mirror 3. On a photoactive face 7 of a photoelectric sensor 6, the real images of the sample 1 and a contrast sample 2 having almost equal magnification are focused. This permits a simpler constitution to reduce the photometry error.
