Why Pulsed Light is better

Pulsed Light can deliver peak energies 100,000 times higher than the sun's intensity on the earth's surface! Why does this work better than continuous light? Because Pulsed Light delivers more photons faster at lower temperatures.

This is analogous to penetrating a block of wood with a nail: one could press a nail into the wood with a finger for 10 seconds without effect, or exert the same amount of energy and drive the nail instantaneously into the wood with a single strike of a hammer. Pulsed Light, like the hammer, delivers light at high peak power for deep penetration.

What is Pulsed Light?

Pulsed Light is high-energy light delivered in incredibly short periods of time. It’s a simple concept with profound ramifications, because it means we can produce extremely large amounts of energy, up to 1 megawatt, while generating very little heat. As a result, Pulsed Light can be used in a wide range of applications where high energy is needed, but high temperatures would damage the materials involved. This has led to breakthroughs in many industries, from optical discs to semiconductors.

The Benefits of Pulsed Light

  • Deeper penetration for complete cures with full and consistent results. Pulsed Light penetrates thick and semi-opaque substrates more effectively than continuous light, improving everything from adhesives and coatings to the inner chemistry of materials.
  • Uses far less power for lower cost of ownership. Light is only produced for a small portion of the typical duty cycle, saving up to 80% on energy use compared to continuous light.
  • Process flexibility. Engineers can tailor key parameters including peak power, pulse repetition rate, pulse sequencing, cure duration, and output spectrum, to achieve the optimal balance of energy, heat, and processing times.
  • Reduced cure time for much higher throughput. Pulsed Light keeps temperatures low even while it delivers high energy, allowing higher throughput for volume manufacturing.
