FIELD: automatics; material analysis. SUBSTANCE: standard dish is mounted in two-beam compensating photometer for movement in two inverse perpendicular directions transverse to optical axis of the device and is mechanically connected with two electric motors. Standard dish is made in form of rectangular triangle prism. Side face of the prism being disposed in perpendicular to optical axis is made of light-absorbing material and has optical density which increases uniformly along the length of the face. Angle of slope of dish side face to optical axis is determined from the relation given in the description of the invention. EFFECT: improved precision of measurement. 1 dwg
