Your OEM Partner for Custom XRF Measurement Windows

If you're an original equipment manufacturer building handheld XRF analyzers, or if you're sourcing components for one, you already know how much rides on a component as small as the measurement window. It's the interface between your X-ray source and every sample your instrument will ever test. Getting the design, the film, and the fit exactly right isn't optional. It's foundational to how your analyzer performs in the field.

Alloy Geek isn't just a retailer of replacement parts. We design, manufacture, and supply measurement windows directly to OEMs from initial concept through full production runs. Whether you're developing a new XRF platform from the ground up or need a reliable manufacturing partner for an existing product line, we build measurement windows to your exact specifications, not the other way around.

Custom Design, Built Around Your Analyzer

Every XRF platform is different, and off-the-shelf components rarely fit an OEM's actual engineering requirements. That's why custom design sits at the center of what we do.

We work directly with OEM engineering teams to develop measurement windows matched to your specific instrument geometry, X-ray tube configuration, and application requirements. Prolene, Kapton, and other film options are available and can be tailored for film thickness, frame design, and mounting configuration based on what your analyzer platform actually needs — not a generic template that happens to be close enough.

Whether you're optimizing for maximum X-ray transparency, extended durability in field conditions, or a specific form factor dictated by your instrument's internal design, our engineering team works alongside yours to get the window right the first time.

Fast Turnaround, From Prototype to Production

Product development timelines don't leave room for months-long lead times on a component this critical. We understand that OEMs need a manufacturing partner who can move at the pace of the development cycle — not one who becomes the bottleneck in it.

From initial prototype samples through full production tooling, Alloy Geek prioritizes fast turnaround at every stage. That means faster design iteration when you're still refining specifications, and reliable, predictable lead times once you're in full production and need consistent supply to keep your assembly line moving.

Built to Handle High and Low Volume Orders

Not every OEM relationship looks the same, and our manufacturing capability is built to flex with that reality.

Launching a new analyzer platform and need a small batch of prototype windows to validate your design before committing to tooling? We handle low-volume runs without forcing you into minimum order quantities that don't make sense for early-stage development.

Running a mature product line that needs consistent, high-volume supply of measurement windows month after month? We scale production to match your manufacturing schedule, with the quality consistency that OEM supply agreements demand.

From a handful of prototype units to ongoing high-volume production, we structure our manufacturing process to support OEMs at every stage of their product lifecycle — without asking you to compromise on lead time or unit cost to get there.

Why OEMs Choose Alloy Geek as a Manufacturing Partner

We bring a unique perspective to XRF component manufacturing: we're deeply embedded in the handheld XRF industry itself, supplying replacement parts, accessories, and reference materials to XRF users across scrap metal recycling, PMI, mining, environmental testing, and precious metals. That means we understand how measurement windows actually perform in real-world field conditions — the wear patterns, the failure modes, the durability demands — and we bring that knowledge directly into how we design and manufacture windows for OEM partners.

When you work with Alloy Geek, you're not just sourcing a component. You're partnering with a team that understands the full lifecycle of a measurement window, from the engineering bench to the field, and builds accordingly.
