[Measurement principle]: Use two templates and related functions to modulate the phase change rate of the measured phase object, express it in the form of stripes, and the relevant parameters of the measured object can be directly determined according to the distribution shape of the stripes.
[Convenient observation]: Observe the lens directly through the mirror on the dial, which is more intuitive. With the light, the imaging is clearer and more accurate. After special lighting treatment, it can effectively protect the eyes.
[Easy operation]: Flexible pressing, adjustable baffle, precise lens layout, high work efficiency and easy use. Help you control your work accurately. Meet any of your usage needs.
[Precise layout]: The appearance design is small and beautiful, the lens layout is precise, and the positioning is fast and accurate. The display screen has no parallax and no deformation.
[Applicable scenarios]: Suitable for various scenarios, including major eyewear stores, vision care centers, hospitals, optometry training centers, etc.
