Getting the Heat Right for Glass R&D
If you’ve ever tried using a standard, off-the-shelf infrared lamp for glass research, you know the frustration. They just blast heat everywhere. It’s uniform. But when you’re messing around with new glass materials, “uniform” is usually the last thing you want. You need control. You need to be able to tell the heat exactly where to go and where to stay away. That’s where we come in. We don’t just make quartz lamps that fit your dimensions; we build them to handle power density exactly how you need it.
How we actually do it
Most lamps just spread wattage in a straight line. Boring. We do things differently. By tweaking how we wind the tungsten filament and adjusting the diameter of the quartz tube, we can basically “map” the heat. We can create hot zones and cool zones all in one single tube. Imagine you have a 500mm tube, but you need a massive spike of heat right in the center without scorching the edges of your sample. We just build the filament to peak right there. You tell us the wattage per centimeter you’re looking for, and we make it happen.
The trade-off (The honest part)
We use high-purity fused quartz because it lets short-wave radiation fly through. The result? Your target hits temperature almost instantly. It’s satisfying. But here’s the catch. When you cram that much power into a tiny footprint to get those rapid heating speeds, the lamp takes a beating. It’s intense. If you don’t have your cooling blowers dialed in, you’re going to burn out your electrodes. Just make sure your airflow is up to the task.
Putting it in your lab
The best part? These are designed to be drop-in replacements. You shouldn’t have to rebuild your entire rig just to get better heat. We offer a handful of connector options so you can get it wired up and running without a headache. Plus, since the heat profile is built into the lamp, you can throw away those clunky mechanical masks you’ve been using to shield your workpieces. No more guesswork. You just get the thermal map your material needs.
