Self Cleaning GoPro Lens

There are situations where it would be nice to have a self-cleaning GoPro lens like any time water or schmoo can splash on a GoPro camera lens. In my situation, I use the GoPro inside a milling machine, and coolant will spray onto the lens.

Looking at the Rotoclear patent for their cameras, the concept is pretty simple.

1. The lens spins on a central motorized axis. It can spin up to 10,000 rpm.

2. The seal between the spinning lens and the housing is a labyrinth-type seal.

3. Positive air pressure is used to keep out liquids, dust, etc. A compressed air line is connected to the camera body housing.

   1. The larger roto-clear window also uses compressed air to keep out liquids and debris.
