Out on the line, nano coatings don’t care about your schedule. If the heat profile drifts, you’re staring at uneven cure, pinholes, and scrap—usually after you’ve already paid for the coating step. Standard broadband heaters fight this because they push convection and surface overheat, not the absorption profile the coating actually needs. What we built into this drying lamp We set it up around near-infrared (NIR) emission that matches the coating’s absorption, not the furnace curve. The quartz envelope gives fast response with tight spectral control, so the energy goes into the film instead of heating the glass bulk. The payoff is a repeatable thermal profile: uniform across the width, stable from start to stop, and consistent shift after shift. The output density is tuned for production speed, so you cure in seconds instead of minutes, and the lamp runs at line pace without chasing temperature swings. Why it lands in glass processing In this work, the scoreboard is yield and cycle time. You get consistent drying that keeps coating thickness uniform, which cuts rework and keeps the line moving. The lamp heats quickly on demand, so changeovers are shorter and smaller batches don’t feel like a headache. Energy use drops because you only deliver what the coating absorbs, and the footprint stays tight—no extra warm-up lane, no idle heaters burning standby power. The things you need to plan for NIR drying is line-of-sight. Coating geometry, glass emissivity, and any shielding fixtures can throw shadows, so we size the lamp and optics to your exact pass and part. Installation is straightforward as a drop-in module, but alignment tolerances are tight—plan on a few minutes to lock beam uniformity and avoid edge hot spots. Get that nailed down, and you’ll run with fewer defects and less scrap.
