    Imaging Aspherical Lens

      The company uses ultra precision molding technology to produce glass aspherical lens for imaging with diameter ≤40mm. Products are widely used in CCTV cameras, automotive cameras, DV, laser equipment,intelligent household and infrared equipment.

      Aspherical lens is an optical element with complex curved surface. Its surface shape is determined by many high order equations. Curvature changes continuously from center to edge. Lens radian can be designed according to different requirements. The aspheric lens can simplify the optical system design and improve the imaging quality in the optical system.


      With the advantages of full industrial chain, the company can meet the demands of different customers, and provide customized products according to customer requirements:

    l  Optical glass raw material production

    l  Aspheric perform manufacture

    l  Aspheric lens precision molding,

    l  Lens coring

    l  Lens coating

    l  Full production capacity

    l  All-aspect optical testing capability
