Abstract: A device for photometering a substance placed in a cylindershaped cell, comprising an aperture diaphragm and an elliptical mirror successively arranged in the path of a light beam emitted by a light source. The elliptical mirror is installed coaxially to the cylindershaped cell containing the substance to be photometered. The light beam, incident on the eliptical mirror and reflected therefrom, is focused on said cell and then collected on a photoreceiver. In the path of the light beam, incident on the elliptical mirror and reflected from said mirror, is arranged a semi-transparant mirror is arranged for directing the light beam passing through said cell to the photoreceiver. The device has low sensitivity to axial displacement of the cell with respect to the optical axis thereof, and also exhibits low sensitivity to rotation of said cell about its axis.
