Stop Wasting Your Heat: Why Gold-Coated Reflectors Actually Matter

If you’re running an IR lamp in wafer processing and you aren’t using a high-end reflector, you’re basically throwing half your power away. It’s a simple problem: lamps radiate energy in both directions. Without a way to push that backward heat back toward the wafer, you’re just heating up the air in your shop. That’s where gold-coated aluminum comes in.

Why gold? (And why not just polished aluminum?)

Now, polished aluminum isn’t terrible. It does the job to a point. But when you get into the long-wave infrared spectrum, aluminum starts to struggle. Gold is different. It reflects IR energy with way more efficiency. We don’t make the whole thing out of gold—that would be insane. Instead, we use a precision-machined aluminum base and coat it in gold. You get the lightweight feel of aluminum but the raw performance of gold. The result? The reflector doesn’t soak up the heat itself; it just bounces it right back where it belongs.
