STATUS ESTIMATION DEVICE, STATUS ESTIMATION METHOD AND PROGRAM FOR ULTRAVIOLET CURABLE RESIN

摘要

A status estimation device for ultraviolet curable resin includes a probe configured to irradiate an ultraviolet curable resin with excitation light, a wavelength demultiplexer configured to receive fluorescence produced from the ultraviolet curable resin and detect spectral distribution of the fluorescence, and a computer configured to estimate status of the ultraviolet curable resin by comparing a shape of pre-irradiation spectral distribution detected when the ultraviolet curable resin is irradiated by excitation light before being irradiated by ultraviolet radiation with a shape of post-irradiation spectral distribution detected when the ultraviolet curable resin is irradiated by excitation light after being irradiated by ultraviolet radiation.
