Abstract
A high brightness excimer light source has an elongated tube containing an excimer-forming gas and electrodes for exciting the gas to form a plasma, and thus create excimers such as a rare gas halogen excimer or a rare gas excimer. Light emitted from the excimer propagating axially along the tube passes out of the tube through an exit device such as a lens or optical fiber at one or both ends of the tube.
Claims24
An ultraviolet light source comprising:
- (a) an elongated tube having first and second ends and an axial direction between the ends;
- (b) an excimer-forming gas disposed within the tube;
- (c) a light exit device mounted adjacent the first end of the tube;
- and
- (d) a plurality of electrodes spaced apart from one another along the length of the tube, the electrodes being constructed and arranged so that upon application of RF energy to the electrodes, an electrical discharge occurs within the excimer-forming gas disposed within the tube, whereby the excimer-forming gas will form excimers within the tube and the excimers will decay and emit ultraviolet light, at least some of the ultraviolet light being directed generally axially within the tube into the light exit device.
2 more elements
A method of providing ultraviolet light comprising the steps of:
- (a) applying energy to an excimer-forming gas disposed in an elongated tube so as to generate excimers in the gas whereby light emitted from the excimers propagate axially along the tube;
- and
- (b) capturing light propagating axially along the tube at one or both ends thereof.
