Lepton® 2.0 by TELEDYNE FLIR
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.
50 degree Lepton DOF/Distance test
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

Tips for integrating Lepton into a Housing
- Recommended Material
- PORON®
- Socket Stack
- Socket > Lepton > Foam > Window > Enclosure
- Maximum Force
- < 1Kg (more force will damage the shutter)
- The foam must be cut out so that it does not interfere with the mechanical shutter pins.
- Thickness
- Depends on the enclosure and spacing, do not exceed 1Kg of force.
Important Information
- PureThermal 1/2/Mini/Pro with Radiometric FLIR Lepton 3.5 requires specialized software to show radiometry such as GetThermal.
- All international customers that are ordering any Thermal Imaging Camera will be required to fill out an End Use Statement document before shipment. Once you place your order we will email you with the document within one business day.
- Important information for customers in Russia. Due to recent US regulations we are no longer able to ship FLIR thermal camera cores to these countries/territories. Any orders containing these products from these countries will be canceled and refunded. We are sorry for the inconvenience.
- We can only ship this product with a Lepton to North America, Australia, and the European Union Countries. Any orders for this product with a Lepton placed in a country other than those will be canceled and refunded. We are sorry for the inconvenience.
