5-3. General Guide for Irradiation Distance and UV Intensity
Set the irradiation distance in accordance with the size of the area to be irradiated (irradiation
diameter) and the required UV intensity. Below is shown the relationship between irradiation distance
and irradiation diameter, as a general guide for setting the irradiation distance and UV intensity.
Relationship between irradiation diameter and irradiation distance of each fiber unit, with UV
intensity of 70% (reference values)
Measured with 1mm diam. sensor
