Figure 1. F300S/F300SQ Lamp System
The F300S/F300SQ Fusion UV Lamp System ( Figure 1 ) is modular, consisting of
independent 6-inch (15.2 cm) lamp units and corresponding modular power supplies.
Two lamps can be placed end-to-end to form a 12-inch (30.5 cm) lamp system or can
be placed in a continuous array to form lamps of 18-inch (45.7 cm), etc. This is
possible because the illumination of the lamp is a full 6". When two 6" lamps are
placed end-to-end forming a 12" lamp, material being irradiated in the focal plane
53.3mm (2.1") below the lamp bottom, and at the juncture between the two lamps,
receives sufficient radiation from each 6" module to provide uniform curing over the
entire region.
Microwave energy from a single magnetron is directed into the cavity formed by an
aluminum reflector and a screen over the bottom of the reflector. The lamp bulb is
located inside this chamber. The screen keeps microwaves inside the chamber but
allows UV light to pass through onto the material to be cured.
