and UV-C regions have more energy and are effective for curing and removal of surface tack for
thin layers of coatings, inks and paints.
To allow the IntelliRay curing system to adapt to these different types of curing applications,
multiple replacement lamp types are available which are optimized for each of the visible, UVA
and UVB wavelength ranges. See the Accessories list in section 10.2 for ordering part numbers
of the optional lamp types.
Refer to the chart below for the wavelength ranges of the ultraviolet and visible light curing
bands of the electromagnetic spectrum.

4.2 System Information
The IntelliRay 600 has a very high-power density light output, which will result in rapid, high
bond strength cures. The light intensity can be adjusted from 35 to 100% of total power using
the unit’s front panel keypad. The intensity can also be controlled somewhat by adjusting the
distance of the lamp head to the substrate being cured (shorter distance results in increased
light density and intensity). The lower intensity settings can be used for very reactive adhesives,
or for temperature sensitive curing substrates.
The IntelliRay 600 utilizes a metal halide type arc lamp, which is powered by a tightly regulated
switch-mode power supply. This combination provides high intensity and consistent light output,
resulting in very fast and repeatable product curing. The system’s timer-controlled shutter
precisely regulates the duration of light exposure to the product being cured. A system block
diagram is shown in Figure 9.
