Getting Your Glass Lehr Heating Actually Right

Most off-the-shelf infrared lamps just don’t cut it when you’re working with specialized glass. If your mix has specific additives, the material won’t soak up heat evenly. It’s frustrating. You’re pumping in energy, but the glass just isn’t taking it. We fix this by tweaking the infrared emission peak so it hits the exact “sweet spot” where your glass additive actually absorbs heat.

The “Why” Behind the Physics

Think of glass as having specific “windows” it likes to open for heat. Depending on what’s in your mix—maybe some rare earth elements or metal oxides—those windows only open at very specific wavelengths. Here’s the problem: if your lamp is pushing energy at 2.0 microns, but your glass only “listens” at 3.5 microns, that energy just bounces off or sails straight through. You’re basically paying for electricity that’s doing nothing, all while fighting those annoying uneven temperature spots. To stop that, we mess with the emitter materials and the coatings. By changing the filament and the quartz envelope, we shift the output to line up perfectly with your chemistry. The result? The heat actually sinks into the bulk of the glass instead of just scorching the surface.
