Professional analysis of optical glass lens molding technology

Optical glass lens molding technique is a precision optical element processing technology, which is the high precision softened glass into a mold, in the elevated temperature and pressure and anaerobic conditions, one of the molded directly achieved using optical parts required. The technology developed since the mid-1980s has been more than ten years of history, has now become the world's most advanced optical components manufacturing technology methods, in many countries has entered a practical stage production.

Popularize the application of this technology is the optical industry in the optical glass parts processing a major revolution. As this technology can directly press molding aspheric optical components, optical instruments will never be created can be widely used aspherical glass optical parts of the era. Therefore, also to the optical instrument optical system design has brought new changes and developments, not only reduces the volume of optical instruments, reducing the weight and material savings, reducing the coating of optical components and the workpiece assembly workload, reduce costs, but also improves the performance of optical instruments and improve the quality of optical imaging. Here is more news on optical glass.

Optical glass molding method does not require the traditional manufacture of optical components roughing, finishing, polishing, and edging centering and other processes, so that parts can achieve high dimensional accuracy, surface accuracy and surface roughness. Can save a lot of production equipment, tooling materials, plant area and skilled workers, so that a small shop can have very high productivity. Can be easily achieved economically precision aspheric optical components for mass production.

As long as the precise control of the process of molding process parameters such as temperature and pressure, we can guarantee the molded optical parts dimensional accuracy and repeatability. Small non- spherical lens may be molded array. Optical components and installation parts can be made into an overall basis.

Now, the world has mastered the art of glass optical components manufacturing technology known companies and manufacturers have U.S. Kodak, Corning Corporation, Japan Ohara, Hoya, Olin Olympus, Panasonic, Germany and the Netherlands Philip Carl companies.

Molded glass optical components technology is an integrated technology, need to design special molded machine tools, molds and selection of high quality and reasonable process parameters. The method of forming the glass types and blanks, mold materials and mold making, molding glass are the key technologies.
