General guidelines for irradiation distance and UV intensity
Fix the LED head to a jig at the appropriate distance from the workpiece, according to the size of the area to be
irradiated (irradiation diameter) and the required UV intensity.
General guidelines for work distance (WD) and UV intensity are offered below.
■ UV intensity data (typical characteristics)
[UV intensity level: 100% Room temperature: 25°C With a cooling device attached]
* See page 11 for the dimensions of the cooling device.

Irradiation distance vs
intensity and area
If an irradiation area of 6 mm diameter
is irradiated at an intensity of 500 mW/cm
2
or higher, draw lines on the graph at ±3 mm
and 500 mW/cm
2
. Find the irradiation
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
2
or higher
for a 6-mm diameter area
by setting the irradiation distance to 50 mm.
