This type of lens tester is used to test the lens of the lens, the refraction prism, the cylindrical axis, the prism and the baseline direction of the prism, as well as the printed marks to the optical center of the lens, the cylindrical axis and the direction of the cylinder bottom.
Instrument reading, clear scale, intuitive and intuitive, high precision, good reliability, simple operation and convenient use.
There is a compensating prism that can correct the center of the light spot, and can measure lenses and mirrors. It is an ideal measuring instrument for glasses manufacturers, shops, and ophthalmologists.
The instrument can be AC, DC dual batteries.
Suit for spectacles measurement detection department, spectacle processing factories,spectacles sales departments,departments of ophthalmology in hospital and optical element factories.
The lens meter is used to measure the spherical diopter, cylindrical diopter and cylindrical lens axis position of the lens, and can print marks on the lens optical center, cylindrical lens axis position and cylindrical lens base direction. Place the lens for measurement, work fine to ensure accuracy Specification: Eyepiece focusing range: ±5D Vertex refraction measurement range: -20D ̃ +20 D Minimum measurement grid: 0.12D Prism measurement range: 5Δ Prism grid value: 1Δ Prism axis range: 1--180º Prism grid value: 1º Products include: 1 * manual lens meter
