FLIR LEPTON With Radiometry Datasheet - Digi-Key

FLIR LEPTON with Radiometry DatasheetDocument Number: 500-0763-01-09 Rev 110General DescriptionLepton with Radiometry is a complete longwave infrared (LWIR) camera module designedto interface easily into native mobile-deviceinterfaces and other consumer electronics. Itcaptures infrared radiation input in its nominalresponse wavelength band (from 8 to 14microns) and outputs a uniform thermal imagewith radiometry to provide temperature imagewith measurements.
