FLIR LeptonFLIR Lepton is a division of FLIR Systems that specializes in thermal imaging technologies, primarily focusing on thermal sensors and imaging components. The main category of components manufactured by FLIR Lepton includes thermal imaging sensors, specifically microelectromechanical systems (MEMS) and uncooled bolometer sensors. These components leverage proprietary technologies to capture thermal infrared radiation and convert it into thermal images for various applications. The Lepton series of thermal sensors is well-known for being compact and cost-effective while offering advanced thermal imaging capabilities.
Notable product lines include the Lepton 2 and Lepton 3, with the latter offering enhanced resolution and sensitivity compared to its predecessors. The Lepton 3, for example, features a 160x120 resolution with a 12 μm pixel pitch and a frame rate of 9 Hz in standard operation, which can be increased to 60 Hz with appropriate processing. These sensors utilize advanced readout integrated circuit (ROIC) technology, allowing for high thermal sensitivity, low noise levels, and operational capabilities in diverse temperature ranges, often from -40°C to 300°C. The integration of digital output interfaces, such as SPI, provides ease of use in embedded applications.
Key features of FLIR Lepton sensors include their lightweight design, low power consumption, and compact form factor, making them suitable for integration into handheld devices, drones, and various automated systems. Common applications span multiple industries, including automotive for driver assistance systems, industrial monitoring for preventative maintenance, healthcare for fever detection, telecommunications for equipment thermal management, and security and surveillance for intruder detection. These sensors demonstrate significant advancements in making thermal imaging accessible and practical across a range of fields, reflecting industry trends towards miniaturization and energy efficiency in electronic components.
