If the lamp can&rsquo;t nail stable peak irradiance on every flash, you&rsquo;ll see uncured tails, adhesion falling off, and scrap piling up fast. Power alone isn&rsquo;t the bottleneck. It&rsquo;s how quickly the electrodes heat, then recover between pulses.</p> <h3 id="what-matters-under-the-hood">What matters under the hood</h3> <p>We built the mercury UV lamp around a low-thermal-inertia cathode, tuned for rapid thermal cycling. The cathode geometry cuts down stored heat, so the arc settles quickly after each ignition. The reflector uses a dichroic coating to push spectral output at 365 nm and keep IR from driving substrate temperature. The payoff is higher peak irradiance (W/cm²) and repeatable dose (mJ/cm²) across the web, even at 1,000+ fpm. Anti-fatigue cathode materials resist <a href="https://o-yate.com">sputtering</a> and the usual end-of-life failure modes, so lamp life stays stable and output drift stays low.</p>
