Injection molding of high-precision optical lenses

In recent years, polymers have undergone great growth in the production of optical components, in special optical lenses such as Fresnel lenses, freeform lenses, aspheric lenses, microlens, or microlenses arrays, and diffractive optical elements, thus far manufactured from glass. Optical polymers allow complex optical designs with several surfaces and various assembly features, previously limited to the demand and high-cost manufacturing processes of glass. These products have been used widely in various fields, such as automotive, lighting photovoltaic, electronics, ophthalmology and medical.
