01 / Product introduction

Product introduction

Built on type-II superlattice (T2SL) technology with a cooled package, this detector is purpose-designed for optical gas imaging (OGI) and industrial thermal monitoring in the oil-and-gas and environmental-protection sectors. It covers the strong absorption bands of methane (CH₄), VOCs and other hydrocarbons, and its high thermal sensitivity and image consistency turn invisible trace leaks into clear, moving thermal imagery — supporting non-destructive inspection and emissions-reduction goals.

02 / Core application scenarios

Core application scenarios

01
Oil-and-gas field and refinery safetyRound-the-clock optical imaging of small gas leaks at wellheads, storage tanks, valves, compressor stations and transfer pipelines.
02
Environmental protection and VOC reductionInspection of VOCs and fugitive methane emissions in industrial parks, and LDAR compliance monitoring.
03
Power and chemical plant inspectionTemperature-anomaly investigation and non-destructive detection of weak heat sources in high-voltage grids, high-temperature reactors and industrial furnaces.
04
Unmanned inspection payload integrationDeep integration into explosion-proof handheld gas detectors, UAV electro-optical gimbals and fixed explosion-proof monitors.

03 / Core advantages

Core advantages

01
Gas-visualisation sensitivityAn NETD of ≤18 mK responds to minute temperature differences and very low gas concentrations, making trace leak plumes clearly visible.
02
Optimised spectral bandA 3.2–3.5 μm gas-tuned absorption band, customisable on request, matches hydrocarbon absorption peaks precisely.
03
High image quality and uniformityAn operability of ≥99.7% and response non-uniformity of ≤8% give a clean, noise-free picture that reduces false positives.
04
Low power, quick responseCooldown of ≤4 min and steady-state draw of ≤4 W meet the endurance needs of portable handhelds and unmanned payloads.
