During the experiment, it is often necessary to measure the distance between some optical equipment to obtain some data. However, it is inconvenient to measure during the experiment, because it is easy to shake the equipment, and at the same time, this measurement method is not accurate enough. The setting of the measurement grid can easily solve this problem. The side length of the measurement grid is 1cm. How many measurement grids there are between them can get the distance between them, which can also improve the accuracy of the data. When doing optical experiments, there will be a separate light source, and the external light will affect the experimental results. All experiments should be carried out in a closed It is carried out in a dark environment, the first sealing cover and the second sealing cover are flexibly connected, and a closed space can be formed by pulling the first sealing cover, which is convenient for carrying out the experiment.
