我厂一台MM6金相显微镜照相系统产生了霉斑,我们采取了下述步骤清除霉斑。 1 首先校对好载物台中心位置,置一测微尺于载物台,使其投影到照相毛玻璃中心位置,见图1所示。清除霉斑后,按装调整时,使测微尺仍复原至图1位置(不可移动载物台)。 2 操作时先定位,后拆卸。拆卸螺钉时,凡有油漆封顶的螺钉,不可拆卸,否则会导致光程偏移。清除霉斑时不可使用酒精、乙醚。 3 拆除左上方的投影屏(图2、3),先将投影屏
I plant a MM6 metallographic microscope produced mildew, we have taken the following steps to clear the mold. 1 First, check the center position of the stage, set a micrometer to the stage, and project it to the center of the photographic ground glass, as shown in Figure 1. After removing the mold, adjust the micrometer to the position shown in Figure 1 (non-movable stage). 2 operation first positioning, after removal. When removing the screws, any screws with a cap on the paint can not be disassembled, otherwise the optical path will be offset. Do not use alcohol or ether when removing mildew. 3 Remove the top left projection screen (Figure 2, 3), the first projection screen
