Getting Your Glass Heat Just Right
Most heating lamps are too simple for glass tempering. They treat the whole surface like one big zone, but that’s not how heat actually works. The edges of your glass lose heat way faster than the center. If you just blast the whole tube with the same wattage, you end up with cold edges and a warped middle. It’s a headache. We handle this by tweaking the power density, not just the size of the lamp.
Mapping the Heat
We don’t just pick a total wattage and hope for the best. We look at exactly where that energy is landing. By changing how the filament is wound or adjusting the internal resistance inside the quartz tube, we can push more heat toward the edges. This cancels out those edge losses. The result? A flat thermal profile across the whole sheet. It’s the difference between a prototype that almost works and one that actually hits your optical tolerances.
Built for the R&D Grind
When you’re messing around with new glass composites, “standard” parts just slow you down. You need room to move. That’s why we give you the keys. You tell us the exact voltage and wattage per centimeter you need. Whether you’re looking for a steep heat ramp or a long, steady soak, we build the lamp to fit your specific thermal curve.
The Honest Trade-offs
Here’s the thing: pushing more power means faster cycles, but it’s harder on the quartz envelope. If you cram too much wattage into a tiny space, you’re asking for trouble—like premature tube failure or “hot spots” that stress the glass. You’ll also need to make sure your cooling system can actually handle the extra heat in the room. We make these units to be drop-in replacements for the rigs you’re already using. Just send over your target temperature map, and we’ll wire everything up to hit those numbers.
