4.2 General guide for irradiation distance and UV intensity

Mount the LED head on the jig so that the irradiation distance is in accordance with the size of the
area to be irradiated (irradiation diameter) and the required UV intensity. Below is a general guide
for irradiation distance (WD) and UV intensity.

If an irradiation area of 6 mm diameter is
irradiated at an intensity of 500 mW/cm
higher, draw lines on the graph at ±3 mm

distance line that covers the area
surrounded by the drawn lines. In this
example, the ANUJ6428 head can
maintain an intensity of 500 mW/cm
higher for a 6-mm diameter area (in the
power mode) by setting the irradiation
distance to 40 mm.
