Description

The FLIR Lepton 2.0 camera core is a long-wave infrared (LWIR) thermal imaging breakthrough in size, power consumption, and price. It currently packs a resolution of 80x60 pixels into a 8.5 x 11.7 x 5.6 mm package that draws only 150 mW nominally. The frame rate is 9 Hz at a spectral response wavelength range of 8 - 14 microns (nominal) and it can be purchased for under $200 in single quantities. Lepton 2.0 is the same thermal imager inside of the first generation FLIR One and the CAT S60 Rugged Smartphone. The new Lepton 3.0 with twice the resolution is available now in our store. Looking for a radiometric Lepton? The Lepton 2.5 is the only radiometric Lepton core available at this time.

The FLIR Lepton is enabling new innovations in industry, science, smartphones, and medicine worldwide. We are proud to have enabled thousands of developers worldwide by being first to make Lepton available in sub-1000 quantities in 2014. We also aim to lower its technical barrier of entry with our custom hardware and open-source software and firmware. Below is a thermal image from Lepton using our latest, the PureThermal 1 FLIR Lepton Smart I/O Module, a hackable USB thermal webcam.











Why use a thermal imager?

Contactless temperature measurement over relatively long distances Human or animal presence detection in day or night Finding hot spots on circuit boards without burning your finger (our favorite) Human position detection in day or night with more privacy offered than a daylight camera (you don't see EVERY detail) Gesture recognition for contactless control in apps like gaming and smart homes Human vs. robot detection Disease and distress detection Search, rescue, and collision avoidance with UAV/UAS and robotics platforms Detecting "motorized doping" Detecting air and fluid leaks

The list above barely scratches the surface of Lepton's potential which is what makes this product special. This technology used to only be available at 10x the cost and in larger package size, heavier weight, and greater power consumption making it not suitable for low-cost and portable solutions.

The FLIR Lepton 2.0 currently comes in three major variants:

50˚ HFOV 50˚ HFOV with shutter and automatic flat-field correction (FFC) ideal for low-noise images especially with static scenes 25˚ HFOV

Development Tools and Accessories

GetLab has designed multiple useful accessories for Lepton applications and development such as the classic lepton breakout board that makes Lepton's digital interfaces easily accessible and the PureThermal 1 FLIR Lepton Smart I/O Module (PT1) that takes Lepton development to a higher level with multiple I/O paths to command, control, and view Lepton imagery. We've also developed a plug-and-play Raspberry Pi 3 kit that allows you to overlay thermal images over the 8MP PiCam daylight images in real time. The kit has a custom (open-source) test program developed with our "pylepton" python library pre-installed to get you quickly up and running quickly. You can download and learn more about our pylepton library to make your own Lepton applications on the kit at our Github link below.
