Getting the Heat Right for Glass R&D
Standard infrared lamps are fine if you just need a general heat load. But when you’re messing around with new glass materials in the lab, “general” doesn’t cut it. You need precision. That’s why we focus on clear quartz tubes where we can actually get creative. Forget just picking a length or a diameter from a list. The real magic happens with the power density—basically, how we distribute the heat along the filament. Controlling the Burn When you’re testing a new glass compound, the temperature gradient is everything. If it’s off, your results are useless. We can customize the filament winding to create specific “hot zones” or smooth, linear gradients. By tweaking the winding pitch and the wire gauge, we put the wattage exactly where you need it. It means you can mimic a massive industrial furnace or trigger a precise thermal shock without having to guess. Why Clear Quartz? We stick with high-purity clear quartz because it lets short-wave radiation pass right through. Instead of just scorching the surface of your glass, the energy actually sinks deep into the substrate. It’s a much more direct way to move energy. One heads-up, though:watch your cooling. When you pack that much power into a small space, things get hot—fast. If your housing isn’t vented properly or your fans are too weak, you’re going to burn out the lamp ends or warp your fixtures. Don’t skip the airflow. No Catalog Constraints We get that lab setups are usually a bit chaotic. Maybe you’ve got a specific power supply you’re stuck with, or a jig that’s way too tight for a standard lamp. We don’t do “standard” if it doesn’t work for you. You tell us the W/cm you’re aiming for, and we wind the filament to hit that number. No fighting with a catalog, no “making it work” with the wrong part. Just a tool that actually fits your thermal map.
