Xenon Corporation has over 40 years of high intensity pulsed UV lamp design and manufacturing to meet industry, research and educational needs. Our engineers are experts at delivering the optimum light footprint for each application.

Many applications require lamp designs that are matched to the target “footprint”. Traditionally, mercury UV lamps have been limited to short arc or linear lamp designs. There are no such limits on pulsed UV lamps. The ability to shape the lamp to the application, providing better uniformity and enhanced matching of the UV light with the substrate, is a benefit for demanding applications.

Illustrating the flexibility inherent in being able to choose the shape of a lamp, is Xenon’s unique spiral lamp* design, specifically developed for Optical Disc manufacturing. The spiral lamp design provides better uniformity and enhanced matching of the UV light across the substrate. Spiral shaped pulsed UV lamps meet the need for fast, low heat adhesive bonding of two polycarbonate discs as well as complete curing of thick top-layer coatings used with new formats such as Blu-ray Disc™.

Critical to the successful use of pulsed UV light systems, is the design of optics, energy discharge components and lamps. Our experience in matching the reflector, lamp and electrical energy components of a pulsed UV curing or sterilization system insures delivering what our customers need - a system best suited for their specific application.

We manufacture all of our many mercury free lamps, for both curing and sterilization applications. In approaching the design of a pulsed UV lamp, we have several options to insure the spectrum best fits the application. One is to select the lamp envelope material to provide a resulting sharp spectra filter. The illustration shows the different transmission characteristics of four lamp types available from Xenon. In general, each lamp material offers features that align with different application requirements. For surface treatment, sterilization and other applications, ozone produced by lamp C and D is useful. All lamp types are interchangeable. Selection of a lamp type, as well as information on lamp spectra, is best done with the help of a Xenon Application Engineer.
