The Teledyne FLIR Boson+ 640 is an uncooled thermal core module from the USA for building into custom payloads and cameras. It is used in mid-sized multicopters, among others in the Skydio X10 aircraft, and supplies the image from which manufacturers build complete thermal cameras.

The detector is an uncooled VOx microbolometer for long-wave infrared (LWIR). It delivers 640 × 512 pixels at a 12 µm pixel pitch. The thermal sensitivity is at most 20 mK, a low value for an uncooled module; the frame rate is 60 Hz as standard, with 30 Hz also selectable. The module weighs 7.5 g without lens. Radiometry, meaning a temperature value per pixel, exists only with selected lens variants, not across the whole series.

At 60 Hz, the frame rate lies above the 9 Hz limit above which thermal modules fall under the EU Dual-Use Regulation. The manufacturer lists the module as ITAR-free with the US export class EAR 6A003.b.4.a and as NDAA-compliant, that is, in line with US procurement rules. An export can require a licence, and data-protection law applies to images of people and property.

As a core module, the Boson+ brings only detector and electronics; lens, housing, image processing and calibration come from the integrator, and measurement accuracy and radiometry depend on them. Anyone needing temperature values chooses a radiometric lens variant deliberately. Points to check are the lens mount, the connection to the image processor and dust on the front lens.

What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
  • Ask about parts availability for this build year — the running costs hang on it.
