Getting the Heat Exactly Where You Need It
Most heating lamps just blast heat everywhere. They’re uniform. But if you’re working in glass R&D, “uniform” is usually the problem. When you’re messing around with new glass compositions or thin-film coatings, you can’t just hope for the best. You need to know exactly where the heat is hitting. That’s why we don’t just look at the size of the lamp—we look at how the power is actually spread across it.
Shaping the Heat
We play around with the filament winding and the wattage to create specific “zones” of heat. Say you need a scorching hot spot right in the center that slowly fades out toward the edges. We just adjust the winding pitch to make that happen. It’s a huge win because you can simulate those tricky thermal gradients without having to tear apart your entire oven or rebuild your jig. You can even tell us the exact wattage per millimeter you’re looking for. It means you aren’t stuck with some generic, off-the-shelf heat pattern that might cause your sensitive glass samples to expand unevenly or just snap from thermal shock.
The Gear
These lamps are built to take a beating from rapid cycling. We use high-purity quartz and some pretty clever coatings to make sure the light matches how your specific glass absorbs heat. Need shortwave IR to hit the surface? Or maybe a broader spectrum to get deeper into the material? We just swap the coating to make it work. And we kept the connections simple. We use R7s or Sk15 bases, so you can just plug them in and go. They’re basically drop-in replacements for most R&D rigs, which means you spend less time swapping lamps and more time actually testing.
One Thing to Watch Out For
Here’s the catch: high power density gets you up to temperature fast. Really fast. But when you cram that much wattage into a small space, your lamp holders are going to feel it. Just make sure your housing can handle the ambient heat rise. You don’t want to find out the hard way that your sockets are melting or your wiring is getting fried.
