Anyone know the resolution of the FLIR camera? Specs don't seem to list the thermal camera resolution, only up-res one. The last revision was kind of weak, low-res with a max of only 120°C or so, if memory serves right. The improvement to : -20°C to 400°C is a happy step forward.

Says "FLIR Lepton 3.5 professional-grade sensor" which lists at 160x120 from https://www.flir.com/news-center/camera-cores--components/flir-lepton-3.5-now-available-to-manufacturers-and-makers/ https://www.flir.com/news-center/camera-cores--components/fl...

  I've played around with both generations of the Lepton sensor and the 3.5 is really nice: factory calibrated so you can directly measure temp without elaborate external calibration and a built-in shutter. Thermal sensors of this type are huge and expensive. At work I also have a Flir with 1024x768 sensor, super expensive with a massive germanium (or something) lens. One of the problems for handheld applications is that you always need two separate optical paths since the lensing is totally incompatible. So you end up having to register the two images to each other, which can fail when it's darkish or the image doesn't have a lot of edges.

  They used a very crappy wordplay to hide the pixels for unknown reasons.

Lepton 2.5 is 80x60, Lepton 3.5 is 160x120. https://www.flir.com/products/lepton/ https://www.flir.com/products/lepton/ Scroll down for full specifications. Key property is also thermal sensitivity, which for Lepton 3.5 is <50mK. Better sensitivity and you will be able to see finer gradients or need less temperature gradient to observe.
