The FLIR Lepton® is a radiometric-capable LWIR camera solution 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 IR sensor or thermal imager. The radiometric Lepton captures accurate, calibrated, and noncontact temperature data in every pixel of each image.

NOTICE: As of 12/31/19 the Lepton 1.5 and 1.6 products will no longer be sold.
