Method for keeping 100-grade cleanness of optical element and packing equipment

The invention provides a method for keeping 100-grade cleanness of an optical element and packing equipment. The method for keeping 100-grade cleanness of the optical element comprises the following steps: firstly, the ultrasonic cleaning and drying are performed for maintaining the 100-grade cleanness of the optical element; then, superior ethanol is used for wiping to remove water in an environment of 100-grade cleanness, and air is compressed for swaying; and finally, the packing equipment is sealed by using a clean film. The equipment for realizing the method comprises the clean film, and the packing equipment for keeping 100-grade cleanness of the optical element. The method and the equipment are suitable for the optical element needed to be stored in a clean environment and needed to keep the original cleanness and the surface grade requirement, are simple in operation, need no additional operation tool, are not restrained by the shape and the specification of the optical element, save the recleaning time loss and risk of the optical element, prolong the service life of the optical element, and guarantee the persistence and the ductility of studies and experiments.
