Let’s Talk Custom Gallium Iodide UV Lamps
If you’ve ever struggled with standard mercury lamps not hitting deep enough into your resins or photoresists, you know the frustration. That’s exactly why we build Gallium Iodide (GaI) lamps. They hit that sweet spot in the 300nm to 400nm range, getting the light where it actually needs to go. Getting the light just right The magic happens with the GaI filling. By tweaking the gas pressure and current density, we can shift the peak wavelength to match your specific chemistry. You tell us the wattage and voltage you’re looking for, and we’ll hit that irradiance level. Just a heads-up: while cranking up the wattage gives you more photon flux, it also generates a lot of heat. If you’re running these at full tilt, you’ll want active cooling. Nobody wants a warped quartz envelope or burnt-out electrodes. Fitting them into your setup We use high-purity fused quartz. Why? Because we don’t want the glass soaking up the UV light before it even leaves the lamp. For the folks building their own equipment, we know the physical fit is everything. We can do custom lengths and end-cap setups so the lamp just slides right into your existing fixtures. Whether it’s a weird pin layout or a proprietary connector, we’ll weld it exactly to your drawings. No guesswork, no “almost fits.” The honest trade-offs Here’s the thing: GaI lamps are specialists. They give you a narrow, targeted spectrum, which is a lifesaver if you’re trying to avoid over-curing the surface. But that also means they aren’t a “do-everything” tool. They’re a bit picky about power. To keep the arc stable, you need a solid power supply. If your voltage bounces around, the spectral peak shifts, and suddenly your curing depths are inconsistent across the line. That’s where we come in. We’ll help you dial in the ballast settings so your lamps stay steady for their entire lifespan.
