Optical dioptrimeter DO-3
Optical dioptrimeter DO-3 Designed to measure the posterior apical refraction and prismatic action of spectacle lenses with a distance from the optical center to the edge of the spectacle lens from 17 to 37.5 mm, plotting the position of the optical center, the position of the main sections for astigmatic lenses and the direction of the main sections for prismatic spectacle lenses. It is used in clinics when selecting glasses and in places where glasses are dispensed to the public. Manba: https://www.nv-lab.ru/catalog_info.php?ID=822
