This is a simple matchbox microscope with single lens and high magnification. It is very convenient to carry and use. The materials are also easy to find: a matchbox shell, a small glass bead (which can be replaced by the small glass bead at the front end of the concentrating electric bead), two match boxes, a small piece of glass, a small glass mirror, and adhesive tape and glue.
The manufacturing process is also very simple. First, the inner box of the matchbox is hollowed out, the horizontal bar at one end is cut off, and a small hole with the same size as glass beads is stuck in the middle of the other end. After the glass beads are put in, cover them with a piece of white paper with a small hole with the same diameter as the glass beads. The first step is completed. Step 2: Open a small long hole of about one centimeter on another match inner box facing the camera, stick a piece of glass on the hole and stick it with adhesive tape, so that the stage is completed. The lens holder only needs to cut a square hole on one side of the trademark as the entrance. The fourth and final step is to install the mirror: stick the adhesive tape on the back of the mirror, fold it back 90 degrees, and stick it on the lower end of the inner box of the matchbox to make the mirror tilt.
When in use, the observed object is placed on the glass on the stage, and then the lens holder is inserted so that the small window faces the light source. By adjusting the height, you can clearly see the magnified object.
