We are planning to apply LS bell hammer to the connector for optical parts to make the connector rotation smooth. Is there a possibility that the lubricant will volatilize or thermally decompose and contaminate the optical components?

With LS Bell Hammer Spray, the connector will rotate smoothly,
When vaporized gas is generated, the effect on nearby parts cannot be said to be zero. (Exhibition temperature 196°C)
However, by utilizing the characteristic of changing the metal composition of the LS bell hammer series,
Even after removing the oil and fat after rotating it for a while after application, the metal is in a state of low friction,
You can expect the effect of smooth rotation and the life extension effect of metal.
