设计的一种仪器已发展到对光学元件表面上的划痕能客观地给予评价。基于激光扫描系统,仪器输出形式为数字显示,可把划痕按强度分成19类。试验证明,这种测量仪器能准确地测出那种只对熟练的检查员勉强看得见的划痕。大多数的光学抛光元件,在向买主交货前至少要求检查一下表面缺陷。检查的有效比例超过制造阶段。要求检查员规定:表面达到高度的抛光,而且还不要划伤、抓伤和碰伤。在保证元件适合用途和买主满意的同时并保持足够的工厂产量当中,检查员担负着重要的测量责任。当要检查的参数(这种情况下为表面缺陷)能够以客观公差定量和标记,但按客观评价和判断检查时,也要费 An instrument designed has evolved to objectively evaluate scratches on the surface of optical components. Based on the laser scanning system, the output form of the instrument is digital display, and the scratches can be divided into 19 categories according to the intensity. Tests have shown that such measuring instruments accurately detect scratches barely visible to skilled inspectors. Most optical polishing elements require a minimum of surface defects to be checked before delivery to the buyer. The effective proportion of inspection over the manufacturing stage. Require inspectors to provide: the surface of a high degree of polishing, but also not scratched, scratched and bruised. The Inspectors bear an important measurement responsibility in ensuring that the components are suitable for use and satisfactory to the purchaser while maintaining adequate plant output. When the parameters to be checked (in this case, surface defects) can be quantified and marked with objective tolerances, they are also subject to objective assessment and judgment
