Optical Lens

There are two production lines in our lens manufacture department to meet different demands. One is the low-speed polishing that is the classic way to produce lenses with high surface accuracy and low roughness requirements. The other is the high-speed polishing which provides more cost effective solution to those lenses with large quantity and fast delivery requirements.
