Claim Text:
1. A status estimation device for ultraviolet curable resin comprising: an excitation light source that emits excitation light; a first wavelength demultiplexer connected to the excitation light source via a first optical fiber; a probe connected to the first wavelength demultiplexer via a second optical fiber; a second wavelength demultiplexer connected to the first wavelength demultiplexer via a third optical fiber; a first detection unit connected to the second wavelength demultiplexer via a fourth optical fiber; a second detection unit connected to the second wavelength demultiplexer via a fifth optical fiber; and an estimation unit connected to the first detection unit and the second detection unit, wherein the first wavelength demultiplexer guides the excitation light incident from the first optical fiber to the second optical fiber, the probe irradiates the ultraviolet curable resin with the excitation light incident from the second optical fiber, receives fluorescence produced from the ultraviolet curable resin, and guides the fluorescence to the second optical fiber, the first wavelength demultiplexer guides the fluorescence incident from the second optical fiber to the third optical fiber, the second wavelength demultiplexer demultiplexes the fluorescence incident from the third optical fiber into the fluorescence of the first wavelength and that of the second wavelength, outputs the fluorescence of the first wavelength to the first detection unit via the fourth optical fiber, and outputs the fluorescence of the second wavelength to the second detection unit via the fifth optical fiber, the first detection unit detects a first intensity at the first wavelength of the fluorescence and the second detection unit detects a second intensity at the second wavelength of the fluorescence, and the estimation unit estimates the status of the ultraviolet curable resin based on the intensity ratio of the second intensity with respect to the first intensity, wherein the status estimation device includes a single probe.
