General Guidelines For Irradiation Distance And Uv Intensity - Panasonic UJ30 Series User Manual

4.2 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.

intensity and area
If an irradiation area of 6 mm diameter
is irradiated at an intensity of 500 mW/cm
or higher, draw lines on the graph at 3 mm
and 500 mW/cm
distance line that covers the area surrounded
by the drawn lines. In this example,
(mm)
the ANUJ6428 head can maintain
an intensity of 500 mW/cm
for a 6-mm diameter area
