Design principle:The company the development of aspheric lens mold, with optical imaging principle to design, according to the principle of this design, can get the best image quality for the user. Aspheric mould design equation:

Analysis:A new generation of aspheric mould with A, B, C three common on the market of aspheric mould contrast (main contrast: ray tracing diagram, like poor figure, focal points in the plane of the figure). Based on analysis of the data are from American ZEMAX optical design software.

Product advantage:

Refractive distribution, thin, beautiful, smooth edge, photometric compensation design, non-destructive optical performance.

Any optimization visual Angle.

, can minimize unwanted distortion error area and brightness.

Panoramic view, optimization design, greatly improve the peripheral vision.

, high precision, high precision surface grinding machine processing, can guarantee the production mold excellent accuracy.
