6 Water Cleaning

Figure 6-1 shows the GUI setting (GUI version: ULC1001 2.4.10) for the LCS. For more info about the ULC1001 GUI, please refer to the tutorial video on ti.com.

Figure 6-3 illustrates the water cleaning performance observed in the water mode operation. It is evident that the majority of water droplets have been expelled; however, fine mist remain along the edge of the lens (dissipate quickly in typical applications). This phenomenon is typical, as the acceleration is maximized at the center of the lens and diminishes to zero at the outer edges.
