FLIR Lepton 2.5 - Thermal Imaging Module

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 small enough to fit inside a smartphone and is less expensive than traditional IR cameras.
With a focal plane array of 80x60 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.
The Flir Lepton thermal imaging modules are used in a vast array of commercial and industrial applications, such as Mobile Phones, Gesture Recognition, Building Automation, Thermal Imaging and Night Vision.
