Patent ID: 7723703

Claim:
A system for multidirectional electromagnetic wave irradiation of an object to be processed having at least one of one, two or more side face irradiation prism systems capable of irradiating a top face and one, two or more side faces of the object to be processed with electromagnetic waves from one electromagnetic wave generation source without moving the object to be processed, and a bottom face irradiation prism system capable of irradiating a bottom face of the object to be processed with electromagnetic waves without moving the object to be processed, the system for multidirectional electromagnetic wave irradiation being characterized in that each of the side face irradiation prism systems has an optical path direction changing prism or an optical path direction changing prism function; the prism systems are provided by the side of an open space for directly obtaining electromagnetic wave irradiation from the electromagnetic wave generation source so that the open space is secured right above the object to be processed, and so that a portion for mount of the object to be processed is secured; the prism systems are placed so that each of the optical paths through which electromagnetic waves entering the prism system from above travel extends via the optical path direction changing prism or the like to reach sideways the side face of the object to be processed, without being obstructed; and the electromagnetic wave generation source is arranged so as to be able to generate electromagnetic waves from right above the prism system toward the prism system.
