Hybrid drying, IR preheat paired with UV curing, only works when the UV energy hits the photoinitiator exactly where it needs to. If the spectral output drifts, curing drags, and throughput falls off.</p> <h3 id="what-matters-technically">What matters, technically</h3> <p>A spectral distribution gallium lamp pins the photoinitiator window with stable output at 365nm, and you can specify 385nm or 405nm peaks depending on the formulation. Peak irradiance at the substrate is typically 800–1200 mW/cm², delivered through a dichroic-coated reflector that shapes the beam and knocks down <a href="https://o-yate.com">unwanted</a> IR. <a href="https://goldisgood.com">Power</a> density is tuned to 80–120 W/cm so the lamp keeps up with line speeds of 20–60 m/min. We track output stability in real time: keep variation under 3% over 8 hours, and target lamp life of 5,000–8,000 hours with controlled end-of-life spectral shift.</p>
