Abstract: An apparatus is provided for delivering energy to a selected area on a surface. The apparatus includes an outlining mechanism which receives light from a light source and directs an aiming beam to a surface, an energy source direction modulator which receives energy from an energy source and directs the energy to the surface, and a controller which causes the outlining mechanism to move the aiming beam relative to the surface to form a visually continuous outline around an area of the surface and causes the energy source direction modulator to deliver energy within the area formed by the visually continuous outline. The apparatus can also include an operator selectable activation mechanism which the apparatus requires to be continuously activated in order to deliver energy.
