High-end metal mould kernel
The spectral optical company lasted more than a year of research and development, the original will be "super precision high-end nanoscale complete sets of processing equipment + + optical polishing process + free surface optical design, optical detection process", the combination of the successful design of the original series of injection molding process, used to manufacture polycarbonate (PC), nylon PA, acrylic PMMA to the lens material such as high-end metal mould kernel products.
NO. 2 well with progressive metal mould kernel type
Far by using gradual type metal mould kernel with wide clear distance vision, suitable for those who need long time in the outdoor, requires a good distance vision, the design in improving long distance vision at the same time guarantee the quality of the close view of. Can design all around eyes, also can be divided into left and right eye eccentric design, can also be designed according to customer's sample, the similarity of 95% or more. ADDS range: ~ + 4.00 + 0.50 D D; Ball photometric + / - 0.05 D, check points astigmatism + / - 0.05 D; Less than 10 nanometers, surface finish of metal mould kernel without an orange stripes and pitting.
