Getting Your IR Peaks Right for Glass Annealing
Here is the problem with standard IR lamps: they’re generic. When you’re working with specialized glass additives, “generic” doesn’t cut it. If the lamp isn’t humming at the same frequency your glass wants to absorb, you’re just throwing energy away. Worse, you end up with uneven thermal stress that can ruin a piece. We fix this by tuning the infrared spectrum to actually match the molecular makeup of your glass. Matching the heat to the chemistry Glass additives change everything about how a material takes in heat. If you just blast it with a standard bulb, you risk scorching the surface while the inside stays cold. To stop that, we shift the spectral output. We play around with the filament composition and the doping in the quartz envelope until the emission peak hits the glass’s absorption maximum. The result? The heat actually sinks into the core of the glass. It’s a much cleaner, deeper soak. The hardware side of things These lamps are built to take a beating from high-density thermal loads. We look at your specific footprint and dial in the voltage and wattage so the filament hits the exact temperature needed for that specific wavelength. If you need to get up to temp fast, we go with a high-wattage setup. But a word of caution:**check your cooling.**Make sure your fans and heat sinks can handle the ambient heat rise. If you don’t, you’ll fry your sockets before you even get to the good part. Putting it to work You can just pop these bulbs into your current annealing ovens or whatever custom rig you’ve cobbled together in the lab. Because the spectral match is so tight, you don’t have to crank the voltage to dangerous levels just to get the glass to soften. It’s a gentler process, which means way less risk of thermal shock. We’ll even send over the emission curves. That way, you can double-check the match against your own absorption data before you ever flip the switch.
