Ultraviolet irradiation apparatus, curing reaction detector used for the same and method for curing an ultraviolet curing resin using the curing reaction detector

摘要

A measured fluorescence amount and a previously set threshold value α1 are compared and when the measured fluorescence amount exceeds the threshold value a1, a message such as "curing reaction completion" is issued. Note that when this "curing reaction completion" is issued, an irradiation end instruction is given to a light source part from a curing reaction detector, and irradiation of a curing ultraviolet ray is stopped. Along with the stop of the curing ultraviolet ray, the irradiation of an exciting ultraviolet ray is also stopped.
