1.概述在光学零件的加工中,对透镜光轴(球面透镜两折射面球心的连线)与几何轴重合性的要求是很高的。一般球面透镜的加工是先留有足够的外径尺寸余量,经细磨、抛光后在磨边机上进行对心、磨边,以获得一定的同心度。但这种方法在加工同心透镜时却带来了困难,因为对于透镜来讲,细磨、抛光后的偏心是指光轴与几何轴的相交角而言,其偏离量随着夹角的增大而增大,这样,也就相应地增加了对零件外径尺寸的加工余量。同心透镜两折射面的球心应在同一点上。若在细磨、抛光过程中 1. Overview In the processing of optical components, the optical axis of the lens (sphere lens spherical refractive index two spherical center of the line) and geometric axis coincidence requirements are high. General spherical lens processing is to leave enough margin size of the outer diameter, the fine grinding, polishing on the edging machine on the heart, edging, in order to obtain a certain degree of concentricity. However, this method is difficult to process concentric lenses, because the lens is concerned, fine grinding, polishing eccentricity refers to the intersection of the optical axis and the geometric axis of the angle, the amount of deviation as the included angle increases Large and increased, so that will increase the corresponding part of the outer diameter of the machining allowance. Concentric lens two refractive surface of the sphere should be at the same point. If fine grinding, polishing process
