Optical instruments are usually composed of metal parts, electronic parts, and optical parts. Moisture intrusion can damage internal parts of the instrument, reducing its service life and even causing safety accidents such as leakage and short-circuiting. Temperature changes can also cause changes in humidity, and excess moisture can condense on the surfaces of optical components, causing mold on mirrors, forming water stains, and affecting imaging quality. Over time, it can seriously cause optical instruments to be scrapped.

The following are some of the challenges that the optical instrument industry often faces:

Optical instruments must be stored and transported in a dry environment, and the temperature and humidity should not change dramatically. It is recommended to place desiccants in the packaging of precision instrument products. If conditions permit, desiccants can be installed directly in the instrument equipment and continuously protect the instrument during operation. For marine exports of precision instrument products, the dramatic change in temperature and humidity are unavoidable. It is recommended to use high moisture absorption desiccant in the container.
