FLIR Lepton 2.5 – Thermal Imaging Module

The FLIR Lepton® 2.5 – Thermal Imaging Module is a radiometric-capable long wave infrared (LWIR) camera solution that is smaller than a dime, fits inside a smartphone, and is less expensive than traditional IR cameras. With a focal plane array of 80×60 active pixels, this Lepton easily integrates into native mobile-devices and other electronics as an IR sensor or thermal image sensor. The radiometric Lepton captures accurate, calibrated, and non-contact temperature data in every pixel.
