Stop Obsessing Over Wattage (And Start Thinking About Power Density)

When people come to us for custom infrared tubes for glass R&D, they usually start the conversation with length and wattage. I get it. Those are the numbers on the spec sheet. But if you’re working with new glass formulations, focusing only on total power is a trap. What actually matters is how that heat is spread across the tube.

Getting the Heat Exactly Where You Need It

We don’t just chop tubes to a certain length and call it a day. That’s too simple. Instead, we play around with the tungsten filament winding and the quartz thickness to build a specific “heat map.” Think about it this way: if your glass sample needs a blast of heat in the center that gently fades out toward the edges, we adjust the winding pitch to match that exact curve. It stops those annoying “hot spots” from popping up—the kind that cause thermal shock or mess up the crystallization of your experimental glass.
