Máy đo tròng JS-700S
The j700 auto lensmeter is applied to measure single vision lenses, bifocal lenses, progressive power lenses(PPL), contact lenses(CL).
It has a measuring unit and display unit, and a printer unit (optional) on the right side. The measuring unit is comprised of a Nosepiece, a Lens Table, a Lens Holder, a cushion framework and a Lens Markr. Below the Nosepiece, there is also a Read Button for recording measured data and a Nose Slider on the Lens Table for measuring Pupil Distance (PD) of spectacles. The display unit utilizes a full-Graphic LCD, displaying measured values of right-eye and left eye lenses at one time, show the function of buttons by diagram and graphically show the point of the lens, and the changeable degrees of PPL. In a word the top focus degree and prism degree of eyeglass lenses and cornea screen lenses, orient the axial direction of prism, locate and mark the center and a axis of the rough lens. It can also be used to check whether the glass is installed properly and measure the penetration ratio of purple light.
