| Content | | The NJC-4 Lensmeter is used to measure the diopters of the 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 the lens, the axis of cylinder lens, and the base direction of shuttle lens. This instrument (Both Ac and Dc are permitted Two 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, AU the lenses and the made glasses can be measured by it, therefore, it is a required and ideal measuring instrument for glasses manufactures, glasses stores and ophthalmological hospitals.
Technical Specifications:
- Eyepiece focusing range: ±5D
- The top point diopter measuring range: 0—±20D
- The minimum measuring square value: 0.125D
- The shuttle lens measuring range: 5A
- The shuttle lens square value: 1A
- The cylinder lens axial range: 0—180°
- The cylinder lens axial square value: 5°
- The maximum diameter of the measured lenses l00m/m
- Power supply: AC 110V-6V DC 3V
- Note: This item is AC 110V; The battery is not included!
| Features:
- Equipped with comprehensive measuring functions, it provides SPH, CYL, AXIS and pupil distance optometry
- Durable and easy to operate
- Easily and intuitively read the sphere focal scale value
- High eco-friendly materials
- Design fitting the face curve and no stimulation
- Easy to take and clean
- Free switch between the cross-cylindrical lens and the rotary prism
- When the rotating risk is turning by the sphere, it can make sphere power adjust 3.00D for big scope.
- It is designed expediently and smartly for a particular cross cylinder. Supporting supplementary lens could increase scope of measurement.
