Lepton Micro LWIR Thermal Camera Modules for Handheld, Mobile, and IoT Devices

Create the next generation of innovative thermal-enabled devices with the most affordable micro-thermal camera module from Teledyne FLIR. Develop with the industry's leading thermal camera manufacturer to reduce risk, cost, and time to market.

The Lepton® is a radiometric-capable longwave infrared (LWIR) OEM camera module that is smaller than a dime, fits inside a smartphone, and is one-tenth the cost of traditional IR cameras. Using focal plane arrays of either 160x120 or 80x60 active pixels, Lepton easily integrates into native mobile devices and other electronics as an infrared (IR) sensor or thermal imager. The radiometric Lepton captures accurate, calibrated, and noncontact temperature data in every pixel of each image.  

Lepton is trusted by engineers, the world's top technology companies, and entrepreneurial developers to expand product offerings and enter new markets. Millions of Leptons have been integrated into commercial, consumer, public safety, and enterprise products worldwide. Integrators should consider their requirements for radiometry (temperature) and imaging resolution when selecting a Lepton.
