Raythink handheld OGI cameras
A lineup of compact, easy-to-use industrial OGI cameras
Ergonomic OGI Cameras for Long Industrial Inspections
Raythink handheld OGI cameras let you see gas leaks at a glance. Compact and ergonomic, they feel natural in the hand and stay comfortable during long inspections. The cameras combine sensitive infrared detection with fast onboard processing, turning raw infrared data into easy-to-understand visualizations of gas plumes and surface temperatures. Built for real industrial work, they provide the reliability, accuracy, and durability needed to get the job done efficiently, whether in a cold warehouse, outdoor site, or hazardous environment.
Choose your camera How Raythink OGI cameras work
Raythink handheld OGI cameras visualize gas leaks by sensing how gases absorb infrared radiation. Sensitive infrared detectors combined with spectral filters tuned to industrial gas absorption bands create a visible contrast between gas plumes and the background. A built-in visible-light camera adds real-world context, helping inspectors see exactly where a leak is located without direct contact. Onboard image processing converts infrared signals into clear visual images, making it easy to identify and document leak locations during inspections.
Applications of Raythink OGI cameras
Raythink handheld OGI cameras are used across a wide range of industrial and environmental applications. They help inspect pipelines, petrochemical plants, and oil & gas facilities, detect leaks in cold storage and cold-chain logistics, and support environmental monitoring or emergency response.

FAQ
Honest answers to important questions
An OGI camera is a device that visualizes invisible gas leaks using infrared imaging. It detects gas by capturing infrared radiation absorbed at specific wavelengths, displaying gas plumes as a visible contrast in the scene. This allows inspectors to identify gas leaks without direct contact with the source.
OGI cameras use an infrared detector combined with narrow band-pass spectral filters tuned to wavelengths where specific gases absorb infrared radiation. When gas passes in front of a warmer or cooler background, it absorbs part of the IR energy, creating a visible contrast that appears as a moving gas plume on the screen.
No. OGI cameras do not measure gas temperature. Gas has no stable emissivity and constantly mixes with the surrounding air. Temperature measurement in OGI cameras applies only to solid objects and surfaces, such as pipes, valves, tanks, and equipment.
OGI cameras detect gases that absorb infrared radiation within their spectral range. Typical examples include methane and other hydrocarbons, sulfur dioxide, ammonia, and refrigerant gases. The detectable gas list depends on the camera’s spectral filter design.
Some OGI cameras are certified for use in hazardous or explosive environments. These explosion-proof (Ex-rated) models are designed to operate safely in areas with flammable gases, such as oil and gas or petrochemical facilities. Always verify the certification of a specific camera before use in hazardous areas.
OGI cameras can be used in a wide range of environments, depending on the model. Gas visualization relies on infrared contrast with the background, not only on ambient temperature.
Yes. OGI cameras can operate in complete darkness because gas visualization is based on infrared radiation, not visible light. The infrared detector captures thermal radiation from the scene and the background, allowing gas plumes to be visualized even when no ambient light is present. If a camera includes a visible-light channel, it may require external illumination for visual context, but gas detection itself does not depend on lighting conditions.
In most cases, no. Standard thermal cameras are designed to measure infrared radiation emitted by solid surfaces and are not optimized to detect gases. Most gases are transparent to the broadband infrared spectrum used by conventional thermal cameras and do not produce a stable thermal signature. OGI cameras use narrow band-pass spectral filters tuned to specific gas absorption wavelengths, allowing gas plumes to be visualized as infrared contrast against the background.
