Molded Glass Aspherical Lens

Glass molding is a precision mold with a specific shape at a certain temperature and pressure. The glass preform is pressed to obtain a high precision, high surface quality optical grade lens, Lenses made with precision molding technology usually do not require cold working and polishing, which reduces raw material consumptions, reduces labor and material costs and enables aspherical lenses to be produced in large quantities at low cost. It has broad application prospects in the manufacture of aspherical optical glass parts and standard micro-optical components.

Uses Molded Glass Aspherical Lens 

Description of Molded Glass Aspherical Lens

The advantage of aspheric lenses over spherical lenses is that one or more lenses can be used to correct problems such as image distortion and misalignment of focus. Through the combination of mold production technology and glass material development technology, it is possible to manufacture precision formed aspheric lens.

Meanwhile, ecoptik China's molded glass aspherical lens can be used in large quantities.

Ecoptik China's aspheric lenses by precision molding are used in digital cameras, pickup lenses, and in the field of optical communications.
