Manual Lensmeter Optical Focimeter Lensometer Optometry Optic Machine ±20D

Introductions:

• The lensmeter is used to measure the lens's spherical diopter, cylindrical diopter, and cylindrical lens axis position, and can print marks on the lens optical center, cylindrical lens axis position and cylindrical lens base direction.

 Features:

• This  Lensmeter is used to measure the dioptres of spherical lens and eylinder lens, the axis of cylinder lens, the strength and the baseline direction of shurle 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 De are permitted Two 5# cells When De) has clear readings and graduations as well as high objective precision and reliabilities except that it can be operated easily and conveniently.
• 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.
