Teledyne Flir Lepton 3.1R: radiometric thermal camera module

The new thermal sensor based on a focal plane array Flir Lepton allows a wider field of view and scene temperature range for people detection and fire monitoring applications.

Teledyne Flir has launched Lepton 3.1R, the first radiometric thermal camera module with a field of view (FOV) of 95 degrees, a resolution of 160×120 and a scene dynamic range of up to 400 degrees Celsius.

“The revolutionary Lepton was the world's first micro thermal camera module integrated into millions of devices, from smartphones to drones”, states Mike Walters, Vice President of Product Management at Teledyne Flir. “The 3.1R model can drive advances in cost-saving and life-saving products, from early fire monitoring in critical machinery, electrical switches and data centers to IoT products for smart factories, occupancy monitoring, smart homes and even elderly care applications.”

The 3.1R sensor is an enhancement for existing Lepton products. Incorporates the same object and space visual perception interface (VoSPI), integrated circuit (I2C) and electrical and mechanical shape and fit that previous models to simplify development. Besides, Lepton is still the thermal sensor based on a focal plane array (FPA) market cost.

All Lepton modules include a thermal sensitivity of <50 mK for an uncooled thermal microcamera. Incorporates numerous patented technologies, like the wafer-level detector packaging, wafer-scale micro-optics, an application-specific integrated circuit (ASIC) customized and a low-cost, easy-to-integrate camera package.

The Lepton family also includes integrated digital processing of thermal images and radiometry, the ability to provide the temperature of each pixel in the scene.

To help reduce development costs and shorten time to market, users can take advantage of an online Lepton integration toolkit with application notes and source code to perform tests on Windows, Linux, Raspberry Pi, and BeagleBone.
