Device for measuring full size of spherical lens on line once

The invention discloses a device for online once measurement of the full size of a spherical lens. The device comprises a lens detection sensing unit, a lens clamping assembly and a display, the lens detection sensing units are installed outside the two opposite sides of the upper portion and the lower portion of a to-be-detected lens in pairs. A to-be-detected lens is clamped on the lens clamping assembly; the display is electrically connected with the lens detection sensing unit and the lens clamping assembly respectively; the lens detection sensing unit comprises a plurality of detection probes and a probe sliding seat assembly. The device can be used for measuring optical elements such as a biconvex spherical surface, a biconcave spherical surface, a concave-convex spherical mirror, a single (concave/convex) spherical mirror and a plane mirror. 本申请公开了一种在线一次测量球面镜片全尺寸装置，包括：镜片检测传感单元、镜片夹持组件、显示器；镜片检测传感单元成对安装于待检测镜片的上方、下方两相对侧外；待检测镜片夹持设置于镜片夹持组件上；显示器分别与镜片检测传感单元、镜片夹持组件电连接；镜片检测传感单元包括：多根检测探针、探针滑座组件。该装置可用于对双凸面球面、双凹面球面
