Minimum thicknesses in rim and centre of lens
GB/T1205-1975透镜边缘及中心最小厚度
2.
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。
3.
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.
"Diverging lens causes the rays of a parallel beam of light to spread out and appear to come form a point, i.e. the rays diverge. It produces a virtual image at its principal focus. Such a lens is thinner at the center than at the edge"
散光镜使一束平行光线散开而形似出发于一点,在其主焦点上产生虚像, 这种透镜的心比边缘薄
5.
bevel/5bevl;`bZvl/n 1 sloping edge or surface,eg at the side of a picture frame or a sheet of plate glass
斜边或斜面（如镜框或玻璃板的边缘）.
6.
Every lens has a mounting flange with which it is attached to the camera body.
每个透镜都有一个安装凸缘，依靠它才能把透镜安装到相机上。
7.
"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
