High Resolution LWIR Micro Thermal Camera Module®

LEPTON SERIES
Lepton is the highest production volume longwave infrared camera module in the world.
Smaller than a dime and cost-effective, Lepton has enabled thermal innovation and has
been adopted by millions of customers. Lepton offers either 80x60 (17 µm) or 160x120 (12µm) pixel resolution, absolute temperature output, multiple field-of-view (FOV) options, andan expanded scene dynamic range for high-temperature scenes.
To reduce development costs and shorten time to market, Teledyne FLIR continuouslyenhances the online Lepton integration toolbox. Application notes such as a dewarping
calibration guide for the Lepton 3.1R with a 95° FOV complement source code for testing on
Windows, Linux, Raspberry Pi, and BeagleBone. Furthermore, the Technical Services teamcan work with customers licensing MyFLIR® application software and image enhancing
MSX® and Vivid-IR™.
Lepton’s low power consumption, unmatched image quality, and integration support enable
innovative product development in mobile, small electronics, and unattended sensors for
smart buildings, fire detection, occupancy tracking, utility and process equipment condition
monitoring, smart home, and more.
