The main function of a prefab clean room is to control the cleanliness and temperature & humidity of the atmosphere that products (such as silicon) contact, enabling the products to be in a good environment for production and manufacturing. This space is what we call a clean room. According to international practice, the dust-free purification level is mainly determined by the number of air particles with a diameter greater than a standard number per cubic meter. That is the so-called dust-free; it is not 100% dust-free, but rather controlled to very tiny amounts. Of course, the standard for dust particles is very small compared to our common dust, but for optical structures, even a small amount of dust will have a very negative impact. Therefore, for the production of optical structures, being dust-free is an inevitable requirement.
