General Description 
Lepton® is a complete long-wave infrared 
(LWIR) camera module designed to interface 
easily into native mobile-device interfaces and 
other consumer electronics. It captures infrared 
radiation input in its nominal response 
wavelength band (from 8 to 14 microns) and 
outputs a uniform thermal image with 
radiometry
 to provide temperature image with 
measurements.
