2. Handling Precautions and Reliability

2-1. (7) Condensation

1. Optical path obstruction
   Note that condensation may form temporarily on the glass surfaces in cases such as when a laser diode is moved quickly from a low-temperature environment to a high-temperature environment, and this may cause the product characteristics to degrade temporarily or dirt to adhere to the window glass surface.
2. Electrochemical reaction
   Avoid using open-package products in the condition with condensation, as this may cause the internal elements to undergo electrochemical reactions to result in degradation of the product characteristics.
