Adaptive shade window for plasma operations

摘要

An observation window is provided for use with a spray booth during a spray coating process where the observation window is located in a position to permit an operator to observe the spray coating process. The observation window is controlled to provide light transmission in the window suitable for the specific spray process being performed. The control can be automatic or operator controlled. The window is adapted to have a different light transmission during different spray processes such as plasma spray and HVOF spray.
