我们理化试验室有一台МИМ-7金相显微镜,原备用灯泡五只,在使用中先后损坏,我们利用原有灯座。在保持光源原来位置前提下,利用废灯泡的灯头焊上国产点光源仪器灯泡,并设法调正其他光源保持在原泡光源的位置以代替原来灯泡,经过试验,达到预期的结果,顺利的解决了这一老大难问题。先取已烧毁的原泡一只,测量好灯丝与灯头金属圈边缘的距离(约为55m/m),然后小心敲碎玻璃外壳及泡内玻璃管,使管内两条电源粗铜丝裸露出来,再使铜丝长度从基部保留一寸左右,剪去多余部分,套
We physical and chemical laboratories have a МИМ-7 metallographic microscope, the original five spare bulb, which has been damaged in use, we use the original lamp holder. In the premise of maintaining the original position of the light source, the use of waste light bulb welding domestic spot light bulb light source, and try to adjust the other light source to maintain the position of the original light bulb to replace the original light bulb, after the test, to achieve the desired results, the smooth solution This is a long-standing problem. First take a burned original bubble, measure the distance between the filament and the rim of the lamp cap (about 55m / m), and then carefully break the glass shell and the glass tube in the bubble to expose the two copper wires in the tube, Then keep the length of copper wire from the base about an inch, cut off the excess part, sets
