OGI330HM packs 10 mK sensitivity into 280 grams — and turns gas leaks into images you can act on.
Why Traditional Gas Leak Detection Falls Short
In refineries, along pipeline corridors, and deep underground, toxic and flammable gas leaks don’t announce themselves.
For decades, the standard response has been the same: send a crew in with handheld sniffers. Point by point. Meter by meter. It’s slow. It’s spatially blind. And it puts people directly in harm’s way.
How do you spot a gas leak — from a distance, without contact, on screen?
The industry needed a different answer. OGI330HM is it.
Optical gas imaging has moved from a premium add-on to a baseline requirement. The question was never whether OGI works — it’s been proven. The question was whether we could make it light enough, sensitive enough, and affordable enough to put everywhere it’s needed. The OGI330HM answers that.
Built on SWaP-C — small size, light weight, low power, high performance, competitive cost — the OGI330HM high-temperature MWIR detector resets what visual gas leak detection can deliver.
How OGI330HM Detects Gas Through Infrared Absorption Signatures
Every gas molecule has a unique infrared absorption fingerprint. Methane, CO₂, CO, VOCs — each absorbs IR radiation at its own characteristic wavelengths in the 3–17 μm band.
The OGI330HM, fabricated on III-V compound semiconductor material, is tuned to watch those exact wavelengths.
When a leak plume drifts through the detector’s field of view, the gas selectively absorbs that infrared energy. The resulting thermal contrast between the plume and the background is rendered by Raytron’s proprietary algorithms as a dynamic visual cloud — showing operators the leak source, dispersion direction, and spread in a single image.
The Advantages of Optical Gas Imaging
Against point-based leak detection, OGI brings four clear advantages: you see the leak directly, you stay at a safe distance, you cover ground fast, and you spend less on maintenance over time. Built for the realities of industrial safety inspection.Why Industrial Operators Are Moving from Detection to Visualization：
Three reasons the OGI330HM is different
Powered by proprietary high-temperature MWIR core technology, the OGI330HM combines high sensitivity, lightweight construction, extended service life, and low power consumption in a single detector core — equally suited to handheld, airborne, and fixed online gas-imaging platforms.
1. 10 mK sensitivity. Nothing slips through.
NETD ≤ 10 mK — double the sensitivity of standard ≤ 20 mK detectors. When a micro-leak produces a thermal signal so faint that conventional hardware ignores it, the OGI330HM catches it. No gaps. No missed calls.
2. Runs warm, so it can be light and last.
Traditional cooled detectors run at 77 K (−196 °C). The cryogenic system that sustains that temperature is bulky, power-thirsty, and wears out fast.
The OGI330HM operates at 150 K (−123 °C) — a 73-degree shift that dramatically lightens the cooling load. Three outcomes:
- ≤ 280 g. Drone-ready. Handheld-friendly. Carry it all day.
- MTTF ≥ 20,000 hours on the cryocooler. Built for continuous industrial duty, not quarterly swap-outs.
- 4 W steady-state. A battery that lasts a shift. No charger chasing.
3. One gas, one band. Four variants, no compromises.
Four purpose-tuned configurations, each spectrally matched to the dominant absorption peak of its target — VOCs, CO₂, CO, or CH₄.
The result: higher signal-to-noise ratio. Cleaner spectral separation. You see the gas you’re looking for, not interference from everything else.
Why Optical Gas Imaging Is Becoming an Industrial Safety Standard
The regulatory direction is clear and accelerating:
- Safety — tighter fugitive emission inspection mandates from the EU to the Middle East to Asia-Pacific
- Methane — EU Methane Regulation. EPA OOOOb/c. National carbon-peak and carbon-neutrality targets. All demand auditable, visual evidence.
- Economics — a week of manual point-checking compressed into a single OGI shift. Fewer people. Lower risk. Higher throughput.
OGI330HM. Safety from a distance.
