在天气阴晴不定,光线强弱经常变化、夜间无电等情况下使用显微镜,很难得到明亮均匀的视野。制作一个简单的显微镜照明装置可解决这一问题。一般显微镜没有集光器,仅装有转盘光阑,用空缸头盒(直径略小于转盘直径),水平剪去剩下2厘米高的部分,在内壁刷上白漆,并在其壁上对称打上两个孔,装置二个1.5伏的灯泡,在盒的底部中央打上一小孔,用2.5厘米长的螺丝代替原来固定转盘光阑的螺 Unstable weather, frequent changes in light intensity, no electricity at night under the microscope, it is difficult to get bright and uniform field of vision. Making a simple microscope lighting fixes this problem. General microscope without concentrator, only equipped with a rotary diaphragm aperture box with empty head box (diameter slightly smaller than the diameter of the turntable), the level of the remaining 2 cm high cut off the part of the brush on the white paint on the wall and its wall Two holes were symmetrically placed, two 1.5-volt bulbs were installed, a small hole was placed in the center of the bottom of the box, a 2.5-cm long screw was used instead of the screw
