Lepton® 3.5 by TELEDYNE FLIR

Description

The radiometric Lepton 3.5 is the latest addition to FLIR’s micro thermal camera family and brings with it some unexpected surprises such as an increased operating temperature range to +80˚C and a massively extended scene dynamic range from -10˚ to +400˚C in low gain mode. Leverage 19,200 (160x120) pixels worth of calibrated radiometric output from this tiny yet mighty microelectronic masterpiece. This significant technology upgrade over its predecessors maintains the same form-factor as the 1.x to 3.0 cores so existing Lepton-based hardware can be easily updated utilizing the same socket.

Lepton 3.5 is fit for prime-time products as demonstrated by the success of the FLIR One Pro and the new Cat S61 Rugged Smartphone that recently won PCMag’s Best of MWC 2018. See our extensive catalog of in-house developed hardware and software resources below to help you create your own prime-time product with Lepton 3.5.

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.
