Stop Wasting Heat: Why Gold-Coated IR Just Works

When you’re working inside a vacuum chamber, you’re fighting a battle with physics. Since there’s no air to move heat around, you’re relying entirely on radiation. If you’re heating silicon wafers and that energy is leaking into the chamber walls, you’re basically throwing power and time down the drain. That’s where the gold comes in.

The trick to focusing energy

Most people start with aluminum reflectors, but here’s the problem: aluminum absorbs a decent chunk of infrared energy. It’s not great. Gold is different. In the infrared spectrum, gold is practically a mirror. By lining the heater housing with a precision gold layer, we aren’t just “reflecting” light—we’re bouncing those photons straight back onto the wafer. It feels like switching from a dim bulb to a spotlight. You get a much tighter heat density on your target without having to crank the voltage and stress your equipment.
