Optical Lensmeter,Optometry Lensometer,Spectacle Lens Scanner, Eyeglass Testing Equipment, for Optics Shops

• Accurate Measurement】This focal meter can accurately measure the optical properties of lenses, such as power, cylinder and axis position. This ensures that patients receive accurate prescriptions during eye examinations.
• Measurement】After connecting to the power supply, press the lens clamp leveler, that is, the switch, and the aperture will appear in the field of view. After adjusting the lens position and the wheel, be sure to ensure that the green aperture remains in the center of the field of view, otherwise the measurement reading will be inaccurate. It is recommended to measure three times.
• Parameters】Lens applicable range: 20-80mm, prism axis angle: measuring range 0-360 degrees, spherical diopter grid value: 0.125D (0-±10D), 0.25D (±10D–±15D), eyepiece adjustment, focal length range: 0-±±15D
• Humanized design】After the measurement is completed, the value can be read directly, the is very simple and fast, the scale is clear, small and portable, more flexible and cheaper than large focal meters, and comes with a storage box
• Service: If you have any questions about this product, please feel free to contact us, we will respond to you within 24 hours!
