一、引言工具显微镜包括小工显、大工显和万工显等,都由3×物镜和测角目镜组成基准测量显微镜,要求3×物镜成像清晰度达视场的60～80％,测角目镜的测角精度在1＇以内,但生产中也会发现,虽测角目镜自身装配达精度要求,但换在不同的物镜上时的测角精度会不同,甚至会超差。作者通过实践和分析,找到了解决办法。二、问题的发现以往评定目镜的测角精度时,用5″精度的直角刀口尺安置在平台上,使尺的一边调
I. INTRODUCTION Tools Microscope consists of a minor work display, a large work display and a million work display, composed of a 3 × objective and a goniometer eyepiece to form a reference measurement microscope, requiring 3 × objective imaging resolution of 60 to 80% of the field of view, goniometry Eyepiece angle measurement accuracy of less than 1 ’, but the production will also find that although the angle goggles their own assembly up to the accuracy requirements, but for different objective lens when the angular accuracy will be different, and even over tolerance. The author found the solution through practice and analysis. Second, the discovery of the problem In the past to assess the measurement accuracy of the eyepiece, with a 5 "precision right angle knife placed on the platform, so that the side of the rule
