FLIR is pleased to announce today the launch of Lepton 3.5, a new member of the Lepton family that adds both radiometry and an enhanced scene dynamic range.  The addition of radiometry and a temp range from -10 to 400° means your makes can accurately read temperatures in a much wider range of applications.  Ready to jump in and buy one?  Get it here.

Lepton 3.5 overview

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 160×120 or 80×60 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.
