Optical instruments manufacturing is an ancient engineering technology, cameras, telescopes and microscopes and other optical instruments in the optical parts (lenses, prisms, etc.) in the processing process, does not produce high temperature and high temperature reflection or high temperature phenomenon, but can To achieve through the high temperature processing of the processing effect, known as the "optical cold processing"

    Optical cold processing of the main processes are: pressure, cutting, milling, grinding, polishing, grinding, bonding, coating and so on.

    Industry downstream products include digital cameras, camera phones, scanners, projectors, rear projection TV, DVD players, bar code readers and other optical instruments and optoelectronic digital products. Optical cold processing mainly for its downstream products processing optical lenses, from the material distinction, there are two categories of glass and plastic. Glass lenses are divided into two types of plane mirror and lens, including flat mirror and flat glass and prism, the lens includes a spherical mirror and aspheric mirror. At present, domestic enterprises aspheric mirror processing is still in its infancy, still with glass spherical mirror for the mainstream products.
