Getting Your IR Spectra Just Right for Glass Additives
Most standard medium-wave quartz heaters just throw a broad curve of energy at whatever is in front of them. For basic drying, that’s fine. It gets the job done. But when you’re working with specific glass additives, that broad approach is a waste. You’re throwing energy away. To really get results, you need the IR emission to hit the exact absorption peak of your material. It’s about precision, not just power. Hitting the sweet spot We don’t just crank up the wattage and hope for the best. Instead, we look at the filament material and the quartz envelope to shift where that energy lands. By tweaking the tungsten filament’s operating temperature and adding specific internal coatings, we can narrow the emission band. The goal? Making sure the photons actually soak into the glass additives instead of just bouncing off the surface or heating up the air in the room. The give and take Now, here’s the thing: customization is always a balance. If we chase a very narrow, high-intensity peak to match a specific chemical bond, you might lose some overall luminous efficiency. You’ll get deeper penetration into the glass—which is great—but the tube itself is going to run hotter. Just make sure your cooling fans or heat sinks can handle the extra heat. You don’t want the quartz bowing or the seals starting to leak because the system is sweating. Putting it into practice We build these tubes for the people doing the actual research. We can adjust the length and diameter so they slide right into your existing setup. No need to rebuild your whole rig; they’re basically drop-in replacements. Plus, we use high-purity quartz so they don’t burn out the moment you push them hard. One quick tip for when you wire them up:keep your voltage stable. If your power drifts, the filament temperature shifts. When that happens, your spectral peak moves, and your absorption efficiency goes right out the window. To make things easier, we give you the exact spectral curve data. That way, you can look at it, compare it to your material’s absorption spectrum, and know for a fact that it’s a match.
