Why we don’t take shortcuts with Vacuum IR Lamp testing

Vacuum chambers are brutal. They’re extreme environments where there’s basically zero room for error. When we’re building infrared heaters for these setups, a tiny electrical glitch isn’t just a nuisance. One single arc or a breakdown in insulation doesn’t just fry the lamp. It can mess up your entire chamber or trip your main power rails, bringing everything to a grinding halt. That’s a nightmare nobody wants.

We test every single tube. No exceptions.

Some shops just sample a few pieces from a batch and call it a day. We don’t do that. Every single tube that leaves our floor goes through high-voltage withstand (Hipot) and insulation resistance testing. Here’s why: in a vacuum, the way electricity behaves changes. The spot where the quartz envelope meets the electrodes becomes a huge risk. A microscopic crack or even a tiny smudge of grease on the glass can cause the lamp to arc. By pushing the voltage past the normal operating limit during our QC, we basically force any hidden flaws to show their face. We’d much rather find a failure in our shop than have you find it in the middle of a production run.
