NJC-4 Lensmeter Focimeter Diameter 20mm-85mm

The NJC-4 Lensmeter is used to measure the diopters of the spherical and cylinder lens, the axis of the cylinder lens, the strength, and the baseline direction of the shuttle lens. It can also stamp the optical center of the lens, the axis of the cylinder lens adn the base direction of the shuttle lens. The Lensmeter measures the lens's spherical diopter, cylindrical diopter, and cylindrical lens axis position. It can print marks on the lens optical center, cylindrical lens axis position, and cylindrical lens base direction. This is a manual lens Lensmeter with a self-calibration function, accurate measurement results, high reliability, and suitable for measuring 20-85mm diameter lenses. This instrument (Both Ac and Dc are permitted Two cells When Dc) has precise readings and graduations as well as high objective precision and reliabilities except that it can be operated quickly and conveniently, AU the lenses and the made glasses can be measured by it, which, therefore, is a vital and ideal measuring instrument for glasses manufactures, glasses stores and ophthalmological hospitals.
