If you&rsquo;re using standard aluminum reflectors, you&rsquo;re probably losing more energy than you realize. It just disappears—absorbed by the metal or scattering off in the wrong direction. That&rsquo;s why we use gold. It sounds fancy, but it&rsquo;s purely practical. We&rsquo;re talking about pushing as much infrared (IR) radiation as possible straight onto the wafer.</p>
