Flashlamps

Matching optical footprint

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, Xenon's unique spiral lamp design 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™.

Pulsed UV Curing

UV

Curing technology consists of pulsed UV curing systems based on decades of industry-leading engineering and experience. These lamps and UV curing systems use ultra-high-peak power UV pulses, not continuous light like other approaches.

Pulsed UV curing produces better, deeper, and faster UV curing, with a host of other benefits as well. Xenon Pulsed UV lamps and systems are widely used by process engineers in markets as diverse as medical devices, Optical Storage, packaging and wood processing.

The unique capabilities of pulsed UV curing technology can solve the most demanding UV curing problems. Pulsed UV curing systems offer an extraordinary range of power and cure times. Light sources can be sized and shaped to fit the user's cure area. In a wide range of applications, pulsed light curing exceeds industry requirements and offers benefits that are distinctive.

Pulsed UV Light Benefits

• High throughput with high yields
• Process flexibility
• Energy efficient for cost savings
• Thermal management
• Spectrum/Formulation flexibility
• Curing thick formulations - deep penetration with ease
• Instant ON/OFF (start-stop-start operations)
• Mercury free safety

Pulsed UV Sterilisation

Pulsed UV

light systems offer high peak power that has have been shown to completely eradicate microorganisms and provide a higher rate of sterilisation than continuous mercury UV exposure. Pulsed UV light is particularly useful in applications where continuous mercury UV is unable to meet the requirements for complete DNA destruction, process speed, penetration, low product temperature, personnel safety and process flexibility. Pulsed UV offers faster processing, little or no product temperature build-up, process flexibility, freedom from toxic lamp materials, penetration of plastic packages, and ease of meeting special lamp configuration requirements. The pulsed UV light process is environmentally benign since it does not create or use volatile organic compounds (VOCs) or create suspended airborne particulates.

DNA Damage

The pulsed UV light causes formation of Pyrimidone dimers in DNA, resulting in genetic damage to cells and their ultimate destruction. Types of damage induced by pulsed UV light are:

1. Photolysis
2. Loss of colony-forming ability (death)
3. Inability to support phage growth (enzyme inactivation)
4. Destruction of nucleic acid

Food and Drug Administration Approves Pulsed UV Light

Code 21CFR179.41 issued by the Food and Drug Administration (FDA), Department of Health and Human Services, approves the use of Pulsed UV light in the production, processing and handling of food.

Key Features

• Total DNA destruction
• Safety
• Inline production
• Temperature integrity
• Process effectiveness
• Process speed
• Process flexibility
• Free of toxic substances
• Worker-friendly (safe and easy to use)
• Minimum space requirements

Vitamin D Enhancement

Xenon Corporation's Pulsed Light system is proven to generate large amounts of Vitamin D in mushrooms, making them more nutritious and offering mushroom growers an edge on the store shelf.

Lamps work in just seconds — not the minutes required by continuous light systems. You save energy, reduce handling time and keep your processing line moving. Xenon's Pulsed Light is the closest thing to real sunlight.

The Dole Company, a leading researcher in the field of food enhancement, has installed a pulsed light system into the manufacturing processes in their mushroom plants to enhance the natural Vitamin D properties of their food product. More research is underway at Dole and other major food producers to find new ways to use light for natural food enhancement, and Xenon, with its pulsed light technology, is working with these industries.

Sintering

The Sinteron 2010 offers greater flexibility for sintering conductive Cu and Ag metallic inks, curing thin-film substrates and for solar and surface modifications. It allows for digitally programmable pulse widths, making it extremely flexible and valuable to process development.

A number of attractive features are designed into this stand-alone system. The pulse width is adjustable in increments of 5µs in the range of 100µs to 2,000µs. With total control of the pulse amplitude and pulse width, the optical energy delivered by the system can be precisely controlled. As the pulse profile is very linear at maximum amplitude, a relationship of 1000J/ms can be assumed. The Sinteron 2010 allows connection for either Spiral or Linear Lamp housings. These can provide optical footprints of 19mm × 305mm or 127mm diameter areas.
