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.
Lepton Features
• Integral shutter configurations
• Configurations with 25°, 50° and 57°
HFOV (f/1.1 silicon doublet)
• LWIR sensor, wavelength 8 to 14 µm
• Arrays with 80x60 and 160x120 active
pixels available
• Thermal sensitivity <50 mK
• Integrated digital thermal image
processing functions, including
automatic thermal environment
compensation, noise filters, non-
uniformity correction, and gain control
• Radiometric accuracy
1
(35°C blackbody)
o High gain: ±5C @ 25°C
o Low gain ±10C @ 25°C
• Radiometric Leptons

digital core, and flexible IO from 2.8 V
to 3.1 V
• Fast time to image (< 1.2 sec)
• Low operating power
o Nominally 160 mW
o 800mW typical during shutter
event (~1s)
o Low power mode 5 mW
• RoHS compliant
• 32- pin socket interface to standard
Molex or similar side-contact connector
Applications
• Mobile phones
• Gesture recognition
• Building automation
• Thermal imaging
• Night vision
