Getting the Heat Exactly Where You Need It: Twin Tube IR Lamps

If you’ve worked in glass R&D, you know the frustration of standard infrared lamps. They’re designed to be uniform. But in the real world of glass science, “uniform” is rarely what you actually want. Usually, you’re hunting for specific thermal gradients. You need to see exactly how a new glass composition handles a stress point or a phase transition. That’s why we don’t just sell tubes with standard dimensions—we build twin tube lamps where you can actually control where the power goes. Designing the heat profile Most tubes you buy off the shelf have a fixed wattage per centimeter. We do things differently. By tweaking how the filament is wound and managing the electrical load across the twin-tube setup, we can shift the heat. Want it concentrated in the center? Done. Need it pushed toward the ends? We can do that too. It means your lamp actually matches the thermal footprint of your sample, rather than you trying to force your sample to fit the lamp. A quick word of caution, though. If you’re cramming high wattage into a short tube to hit those extreme temperatures, your housing is going to feel it. High power density puts a lot of stress on the quartz envelope. If your cooling airflow isn’t dialed in perfectly, things can go south quickly. Why the twin tube design works The beauty of the twin tube setup is that you get double the emitting surface area without taking up more space. But it’s not just about raw heat. It’s about stability. We can wire these so you have independent zone control, which gives you a much tighter grip on your ramp-up and soak times. We also use high-purity quartz. This ensures the shortwave emission actually sinks deep into the glass. It stops that annoying “surface skin” effect where the outside of your material melts while the core is still cold. Making R&D a bit easier When you’re researching new materials, you need the freedom to experiment. Imagine testing how a new formula reacts to a 50W/cm profile and then switching to 150W/cm without having to tear down and rebuild your entire furnace. You just swap the lamp. We’ll help you map out these distributions so you aren’t guessing. You’ll know exactly where the heat is hitting your target.
