Aerial thermography with optris PI LightWeight

The newly developed optris PI LightWeight is a market innovation which allows for radiometric recordings of video imagery from the air. The combination of a miniature lightweight PC and a light version of the optris PI thermal imager weighs only 380 g. The PI LightWeight is therefore ideally suited for maintenance work and quality inspections of solar and wind power systems and also for thermographic surveys of buildings.

Important specifications

  • Full radiometric IR inspection with up to 640x480 pixels
  • GPS and GoPro support
  • Automatic transfer of flight videos (IR and GoPro) to USB flash drive
  • Weight: 380 g
    (PI camera + Recording Box)

optris PI LightWeight for flight thermography

The optris PI LightWeight has been especially designed for aerial thermographic inspections. Mounted on a UAV, the optris PI Lightweight allows recording of radiometric IR images and videos. The flight thermography system is therefore eminently suitable for error detection and quality inspections of solar farms and wind power systems. The innovative combination of a lightweight mini PC and a thermal imaging camera is also ideally suited for thermographic analyses of hard-to-reach places like roofs of buildings (building thermography) and it is already in use in agriculture where fields are being inspected before being mowed (presence detection)

Thermography software optris PI Connect included

All IR cameras are delivered with the thermography software optris PI Connect, which has been developed specifically for the extensive documentation and analysis of thermal images. It allows you to analyse temperature data in real time as well as the remote control your your infrared camera. Furthermore you can setup individual alarm levels you need for your process and define visual or acustic alarm signals.

Our thermography software is licence free and can easily be adjusted to your requirements.
