An extremely specialised type of an infrared or thermal imaging camera is an optical gas imaging camera. A viewfinder or screen is used by the user to view the image captured by the camera, along with a lens, a detector, some electronics to analyse the signal from the detector, and other components.
OGI cameras use quantum detectors, which need to be cooled to cryogenic temperatures (about 70K or -203°C). Indium antimonide (InSb) detectors are frequently used in the 3-5 m range by midwave cameras to detect gases like methane.
In order to detect gases like sulphur hexafluoride, longwave cameras typically operate in the 8–12 m range and employ a quantum well infrared photodetector (QWIP).
The materials that make up quantum detectors contain electrons of various energies when they are at normal temperature.
Since the electrons in the conduction band are free to migrate and the material can conduct an electrical current, some electrons have enough thermal energy to be in this band.
However, the majority of the electrons are located in the valence band, where they are unable to travel freely and so cannot carry any current.
The thermal energy of the electrons may be so low that none can enter the conduction band when the material is cooled to a low enough temperature, which varies depending on the material selected.
The substance is therefore unable to carry any current. The energy of incident photons excites electrons in the valence band, pushing them up into the conduction band when these materials are exposed to them and the photons have enough energy to do so.
The material (the detector) can now carry a photocurrent that is inversely correlated with the radiation intensity of the incident beam.
The Global Optical gas imaging camera market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The Most Compact Uncooled Optical Gas Imaging Camera is Launched by Opgal.
The EyeCGas Mini, a new uncooled optical gas imaging (OGI) camera from Opgal Optronic Industries Ltd., is intended to find medium-sized to big leaks.
available for a variety of gases including methane, SF6, ammonia, and HFCs. To provide improved solutions through software-based applications for the new EyeCGas Mini platform and product range, Opgal is willing to collaborate with key industry partners.
An uncooled thermal camera from Opgal has been integrated into a small, powerful Android-based device made specifically for OGI applications.
A wider range of consumers will have access to equipment for Leak Detection and Repair (LDAR) applications because of this thermal camera’s portability and affordability.
With live streaming for real-time remote sharing, image fusion (using visible and infrared cameras) for improved leak location and visualisation, and built-in GPS, the EyeCGas Mini optical gas imaging camera is a feature-rich gadget.
Additionally, the camera has thermography with a variety of colour palettes, a battery life of more than five hours, and only weighs 600g (1.3lbs).
The Android-based EyeCGas Mini enables the quick development of additional functionalities. The consumer will always have access to the most modern technologies thanks to a straightforward upgrading process.
The best tool for technicians performing long-term fieldwork at remote locations is EyeCGas Mini
The most recent addition to Opgal’s already substantial lineup of gas imaging products is EyeCGas Mini. A cooled intrinsically safe OGI camera called EyeCGas 2.0, fixed monitoring systems called EyeCGas 24/7, and quantification and alerting software called EyeCSite are additional solutions.
