Some are flared-that is, thicker at the rim than in the center, like a concave lens.
有些呈喇叭形──即边缘较中心厚，类似凹透镜。
4.
The focal length differs with the thickness of the lens
焦距长底随透镜的厚度而变化。

Relation Between Gathering and Scattering of Thick Lens and Its Thickness;
厚透镜的会聚性和发散性与其厚度的关系
6.
The principal points of a thin lens coincide at the center of the lens.
薄透镜的两个主点与透镜中心相重合。
7.
The side of a lens is curved. The middle part of some lenses is thicker than the edge. In other lenses, the edge is thicker than the middle part.
透镜的面是曲线型的，有些透镜的中间比边缘厚，有一些透镜的边缘比中间厚。

"Converging lens caus3es the rays of a parallel beam of light to come closer and pass through a point, i.e. the rays converge. It produces a real image at its principal focus. Such a lens is thicker at the center than the edge"
聚光镜使一束平行光线愈聚愈拢而通过同一点,在其主焦点上产生实像,这种透镜的中心比边缘厚
