Abstract
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.

A method of protecting the vision of a spray booth spray process operator, the method comprising:
- providing an observation window for use by the operator;
- selecting a spray process;
- and
- controlling light transmission through the observation window as a function of the selected spray process to prevent transmission of ultraviolet light through the observation window.
A spray booth window for use with a spray booth for spray coating an object, the window comprising:
- the observation window being positioned to permit an operator to observe the spray coating from outside the spray booth;
- and
- a control for adjusting the light transmission of the observation window as a function of a selected spray process.
In a spray booth having at least two spray process guns, a place to mount a part to be spray coated, and a control panel for controlling a spray process, the improvement comprising:
- an observation window positioned to permit an operator to observe the spray process from outside the spray booth;
- and
- a control for adjusting the light transmission of the observation window.
