QL40-OBI2G-UV Optical Televiewer with UV Imaging

The QL40-OBI2G-UV probe is an advanced optical televiewer designed to capture both visible light and high-sensitivity UV images of subsurface lithologies and soils within a borehole. It emits 365 nm UV LED light through a sapphire window to induce fluorescence in non-aqueous phase liquids (NAPLs), such as petroleum hydrocarbons.

Key Features:

• Dual Imaging Capability: Simultaneously captures visible and UV-induced fluorescence images at 30 fps for detailed subsurface analysis.
• High-Resolution Imaging: Utilizes a CMOS camera to provide 24-bit RGB true color with 1800 azimuth resolution, delivering precise pixel-by-pixel image capture.
• Advanced Data Collection: When used with the OIP interface, FI6000 instrument, and a laptop, the system collects data on electrical conductivity (EC), penetration rate, fluorescence area (%), and optical power content (%).

Applications:

• Environmental Studies: Detect and map NAPL migration in subsurface materials, enabling horizontal and vertical tracking of petroleum hydrocarbons.
• Hydrogeological and Geological Assessments: Ideal for assessing risks and hazards posed by contaminants.
• Petroleum Research: Proven effective in distinguishing fluorescence variations among different fuels, such as diesel, gas, and crude oil.
• This versatile tool enhances borehole analysis by combining high-resolution optical imaging with UV fluorescence capabilities, making it an invaluable instrument for environmental, geological, and hydrogeological studies.
