Teledyne FLIR achieves 'world first' with latest camera module

Lepton 3.1R

Teledyne FLIR has released what it says is the world’s first radiometric thermal camera module with a 95-degree field of view (FOV), 160 x 120 resolution, and a scene dynamic range of up to 400°C.

The new Lepton 3.1R offers a compact and low-power form factor, making it suitable for mobile, small electronics, and uncrewed systems. It offers a drop-in enhancement for existing Lepton-based products, and incorporates the same visual object and space perception interface (VoSPI), inter-integrated circuit (I2C), and electrical and mechanical form as its predecessors.

Teledyne FLIR says the wider FOV and scene temperature range of the 3.1R makes it suited to people, fire, and condition monitoring applications.  

“The revolutionary Lepton was the world’s first thermal micro camera module integrated into millions of devices from ruggedised smartphones to drones,” said Mike Walters, Vice President of product management at Teledyne FLIR. “Lepton 3.1R can now propel advancements in cost-saving and lifesaving unattended products ranging from early fire monitoring of critical machinery, electrical switchgear, and data centres to IoT products for smart factory, occupancy monitoring, smart homes, smart appliances, and even elderly care applications.”

All Lepton modules offer thermal sensitivity of <50mK for an uncooled micro thermal camera. They also feature wafer-level detector packaging, wafer-scale micro-optics, a custom application-specific integrated circuit (ASIC), and overall represent a low-cost, easy-to-integrate camera package. The Lepton family also includes integrated digital thermal image processing and radiometry, enabling it to provide the temperature of every pixel in the scene.
