Principle of rain-wash coating

With a conventional dome camera, water droplets that remain on the dome cover with exposure to water take a globular shape, which blur the field of view.
However, with the application of rain-wash coating, water droplets on the camera dome become flat, which then minimize blurring to the camera’s field of view and allow for clearer visibility.
In addition, the coating resists attachment of dirt to the dome cover, and also allows dirt to be washed off easily during rainfall or other exposure to water.
