《GB/T 7242-1987透镜中心误差》由TC103（全国光学和光子学标准化技术委员会）归口，主管部门为中国机械工业联合会。
本标准适用于由球面与球面或球面与平面组成的且具有旋转对称边缘面的单透镜和胶合透镜。对于具有其他边缘形状的透镜(例如：矩形透镜)也基本适用。

Scope

This standard applies to single lenses and cemented lenses composed of spherical and spherical or spherical and flat surfaces with rotationally symmetrical edge surfaces. It is also basically applicable to lenses with other edge shapes (eg: rectangular lenses).
