Getting Power Density Right for Glass R&D

If you’ve ever tried using a standard, off-the-shelf infrared lamp for glass R&D, you know the frustration. Most of them just blast heat in a generic pattern. But when you’re developing new materials, “generic” doesn’t cut it. You need to know exactly where the energy is hitting your workpiece. For us, it’s not about how long the tube is. It’s about the depth and the distribution of that power.

The problem with “cold spots”

Here’s the thing: standard IR lamps usually have cold spots at the ends. If you’re forming quartz tubes, those spots are a nightmare. You end up with uneven viscosity across the melt, and your results are all over the place. We fix this by rethinking how the filament is wound and how the wattage is spread out. By packing the power into specific zones, we can create a precise thermal gradient. It lets you see how a new glass composition handles a sudden heat spike versus a long, steady soak. It’s the difference between guessing and knowing.
