Getting Your Gallium Iodide Lamps Right
If you’re working with photoresists or semiconductor processing, you know that “close enough” doesn’t cut it when it comes to UV wavelengths. That’s where our gallium iodide lamps come in. We build these specifically for the tough stuff—the high-intensity jobs where you need a very precise hit of UV to get the chemical reaction you’re after.
The Power and the Heat
Here’s the thing about the gallium halide fill: it hits a different part of the UV spectrum than your run-of-the-mill mercury lamps. When we talk about wattage and voltage, we’re really talking about how dense that plasma is inside the tube. Now, cranking up the wattage gives you a massive flood of photons, which is great for speed. But there’s a catch. More power means more heat. If your housing doesn’t have plenty of airflow, you’re risking a nightmare scenario where the quartz softens or your electrodes just fry.Keep them cool, and they’ll last.
The Glass and the Fit
We use high-purity fused quartz because we don’t want the glass soaking up the UV light we’re trying to push out. If you’re dealing with a corrosive environment, just let us know. We can beef up the envelope thickness to handle the stress. We also make sure the end-caps and pins fit your existing fixtures perfectly. Why? Because a loose electrical contact is a recipe for disaster. It creates a hot spot that can crack the seal in a heartbeat. We machine our electrodes with precision so you don’t have to worry about that.
Let Us Handle the Heavy Lifting (OEM)
If you want these lamps under your own brand, we’ve got you covered. You decide on the size and the electrical footprint, and we’ll take care of the messy parts—the vacuum sealing, the halide filling, all of it. We’ll hand over the raw data sheets so your customers know exactly what the voltage and current draw are. Just a heads-up: if you change the length of the tube or tweak the wattage, the light spectrum shifts. It’s just physics. We’ll run everything through our lab to verify those shifts before we start your full production run, so there are no surprises when you flip the switch.
