Some chemicals, including Freon substitute detergent could corrode, oxidize, cloud or crack the optical characteristics of the lens or the casing surface.
Please review the reference chart below carefully before cleaning.
If water needs to be used for cleaning (including the final cleaning process), please use pure water (not tap water), and completely dry the component after use.

Please keep each cleaning process under 3 minutes at temperatures adjusted to the detergent used (Typically 30 to 50).
When using ultrasonic waves, the bonding wire in the package can have an effect on the resonance reliability.
Please take care that the device doesn't touch the vibrating source directly, and ensure that it will not cause problems in production before using it.
Resonance is usually known to occur at around 10-20KHz, but before using the device, please take into account that, this range will vary depending on the bath design and device position.
