The Uses And The Features
Model NJC-6A Lensmeter is used to measure the dioptres is spherical lens
and cylinder lens, the axis of cylinder lens, the strength and the baseline
direction of Shuttle lens .It can also stamp the optical center of lens, the axis of
cylinder lens and the base direction of shuttle lens.
This instrument (Both AC and DC are permitted.Two5# cells when DC ) has
clear readings and graduations as well as high objective precision and
reliabilities except that it can be operated easily and conveniently. In addition,
it has the compensation lens to correct the optical center .AU the lenses and
the made glasses can be measured by it, which, therefore, is a required
and ideal measuring instrument for glasses manufacturers, glasses stores and
ophthalmological hospitals.
