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. 1 type of progressive metal mould inside the kernel
Universal in the progressive metal mould kernel is a popular design, it has a relatively wide using area near and far zone, connection channel also has good performance, fully in accordance with established photometric design, regardless of a customer different face and the parameters of the frame, convenient and quick, can well meet the requirements for visual client is not very high, is a series of economical design. 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.
Universal type in step 2 channel ADDS + 12 + 250
