Model ALS**3 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 ***** 5# cells when DC) has clear readings and graduations as well as high objective precision and reliabilities except that it can be operated easily and ***** addition, it has the compensation lens to correct the optical point 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. Technical parameter: ***** focusing range:±5D ***** top point dioptre measuring range:**5D~**5D ***** minimum measuring square value:0.**5D ***** shuttle lens measuring range:*0△ ***** shuttle lens square value:1△ ***** cylinder lens axial range:****0° ***** cylinder lens axial square value:1° ***** maximum diameter of the measured lenses:**0mm ***** lighting:AC **0v/**0v*6v    DC 3v YOUTUBE *****/watch?v=Gfh*3NNiaPY
