Dymax BlueWave® LED Prime UVA User Guide
Intensity Control Feature
The components used in all curing systems degrade with use. Intensity, therefore, decreases as the system
ages. The
BlueWave LED Prime UVA’s
intensity control allows for compensation to address this slow
degradation. Users can eliminate this variation by manually increasing output intensity to offset this
degradation. The intensity can be adjusted with a tool as shown in Figure 2Figure 2. Intensity . The intensity
adjustment is a 10-turn potentiometer and allows fine control of output intensity. This feature is useful for
both validation and control.

Validation
Tests should be conducted prior to production to determine the time and light intensity required to fully cure
your light-curable material in your specific application. The following approaches may be used to validate the
curing process.
Set Exposure Time, Determine Intensity
Users can specify a cure time, and through empirical testing, determine the intensity required to achieve a full
cure. As with any manufacturing process, it is advisable to incorporate a safety factor.
Set Intensity, Determine Exposure Time
Users can specify light intensity and through empirical testing, determine the exposure time required to
achieve a full cure. As with any manufacturing process, it is advisable to incorporate a safety factor.
Control
Process validation confirms a minimum acceptable intensity. Users can then choose to operate at a higher
available intensity level (using the additional intensity as a cure safety factor) or adjust the output to a specific
intensity level. To insure consistent and repeatable process results, it is advisable to monitor intensity levels
with the use of a radiometer. This allows identification of any potential maintenance requirements or intensity
adjustment necessary.
