Description
Иммерсионна жидкость заливаетс в резервуар до уровн А-А и имеет .показатель преломлени , равный показателю преломлени материала измер емого оптического элемента с погрешностью не более 0,02, Такое совпадение показателей преломлени практически устран ет преломление лучей на внешней поверхности линзы,The immersion liquid is poured into the reservoir to the level A-A and has a refractive index equal to the refractive index of the material of the measured optical element with an error not exceeding 0.02
Держатель установлен в параллельном пучке лучей, создаваемых источником 1 с помощью системы 2 формировани пучка, так, чтобы предметна плоскость объектива 5 совпадала с плоскостью сечени измер емого элемента 4.The holder is installed in a parallel beam of rays generated by source 1 using beam forming system 2, so that the objective plane of lens 5 coincides with the section plane of the measured element 4.
Применение предложенного устройе-тв а и проектора с увеличением 50х даёт возможность измер ть координат контура вогнутой поверхности контак ной линзы с погрешностью не более 0,003 мм при общем диаметре линзы 10 мм.The use of the proposed device and the projector with an increase of 50x makes it possible to measure the coordinates of the contour of the concave surface of the contact lens with an error of no more than 0.003 mm with a total lens diameter of 10 mm.
