    • There is provided a plastic lens, a lens module and a lens injection mold. The plastic lens includes an effective aperture portion being an optical surface of the lens and a rib portion being a circumferential portion of the lens. The effective aperture portion and the rib portion are shaped in concentric circles having the same central axis. The rib portion includes three or more concave portions in an outer circumferential portion thereof, the concave portions being positioned to be symmetrical with respect to the central axis. The plastic lens is designed to be symmetrical with respect to a concentric axis so that it may avoid asymmetric contraction inside a barrel. Also, since the concave portions, when assembled in the barrel, do not contact an inner circumferential surface of the barrel, press-fitting force in the assembly thereof is reduced so that deformation caused by excessive press-fitting force applied thereto may be avoided.
    • 提供塑料透镜,透镜模块和透镜注射模具。 塑料透镜包括作为透镜的光学表面的有效开口部分和作为透镜的圆周部分的肋部分。 有效开口部分和肋部分成形为具有相同中心轴的同心圆。 肋部在其外周部分包括三个或更多个凹部,凹部相对于中心轴线对称。 塑料透镜被设计成相对于同心轴对称,使得其可以避免桶内的不对称收缩。 此外,由于凹部在组装在筒体中时不与筒体的内周面接触,因此其组装中的压配合力降低,从而可以避免施加于其上的过大的压配力引起的变形。

    • A method of fabricating a liquid lens which can prevent unstable movement of liquids while sealing a hole containing the liquids by applying voltage to a chamber containing the liquids to induce electrowetting, and a liquid lens fabricated thereby. The method includes providing a chamber with a hole formed therein for containing liquid and injecting two non-miscible liquids with different refractive indices. The method also includes placing a conductive transparent plate to be in contact with the liquid on the top and applying voltage to the conductive transparent plate and the chamber to induce electrowetting, thereby changing the shape of meniscus between the two liquids. The method further includes covering an upper surface of the chamber with the conductive transparent plate to seal the hole.
    • 一种制造液体透镜的方法,其可以通过向包含液体的室施加电压来密封包含液体的孔来防止液体的不稳定运动,以引起电润湿,以及由此制造的液体透镜。 该方法包括提供一个室,其中形成有用于容纳液体的孔,并注入两种具有不同折射率的不可混溶液体。 该方法还包括将导电透明板放置在与顶部的液体接触并且向导电透明板和室施加电压以诱导电润湿,从而改变两液体之间的弯液面的形状。 该方法还包括用导电透明板覆盖室的上表面以密封孔。
