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
1
to provide temperature image with
measurements.
Lepton Features
