国产 XJX-1型金相显微镜,附有 Z 型显微摄影仪(上海照相机厂出品)。在摄影组合应用时,它的放大倍数往往不是一个整数。例如:当物镜为8×,摄影目镜为6.4×(Z 型摄影仪自身放大倍数为1.6×)组合时,投影的放大倍数只能放大到82×。由于在金相检验中,经常需要摄制100×的放大照片,以便与有关的金相标准进行比较。上述装置显然不能满足生产检验需要。为了充分发挥这台国产设备的作用,使之能拍摄100×的金 Domestic XJX-1 type metallographic microscope, with a Z-type micro-camera (Shanghai Camera Factory produced). When applied to a photographic composition, its magnification is often not an integer. For example, when the objective lens is 8 × and the eyepiece is 6.4 × (Z-type self-magnification is 1.6 ×), the magnification of the projection can only be enlarged to 82 ×. Due to the metallographic examination, it is often necessary to produce a 100 × magnified photograph for comparison with the relevant metallographic criteria. Obviously the above device can not meet the needs of production inspection. In order to give full play to the role of this domestic equipment, so that it can shoot 100 × gold
