Prices are good, I'd consider one but I'm unsure of what the extra customs charges would be on top for the UK. Any UK member with one?
As the lens is interchangeable can you not just screw it out a bit to get closer focus?
For anyone considering a Therm-App for electronics work, here is a demonstration of the closest macro focus achievable with the stock lens. It's of a Samsung mSATA SSD, approx 50mm across.
(...)
1. Convert your raw Therm-App image with the FLIR calibration reversed. This is done with imagemagick's convert command. The command is: convert input.png -resize 200% -flop -fx "(((17711.559/((EXP(1447.2/(((u*65536)/100)+273.15)))-0.57999998)/0.025931966)+4096))/65536" out.png
This is assuming your temperature is stored as degrees C x100. I will update this once a more completed app is avaliable that outputs raw data.
Note this also flips the image horizontally (because the raw images are horizontally flipped) and upscales 200% (because FLIR Tools can't upscale for saving).
2. Insert this raw image into the FLIR image I linked above. This is done with a php script called "splitjpg.php" created by tomas123. It was originally intended for use with stitching FLIR camera panoramas in external software. You can download it here: https://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-teardown/?action=dlattach;attach=76829
Please note you will need php installed for this. Now run "php splitjpg.php -i flir1.jpg -r out.png -o flirout", where flir1.jpg is any of the files that I've posted here, out.png is the image outputted by imagemagick, and flirout (.jpg will be added automatically) is the resulting file that can be opened with FLIR Tools. Please note the preview image on the file will be incorrect - this will be corrected once we open it in FLIR Tools.
3. Open the file with FLIR Tools. Press "auto" for scaling, as right now it's reading some predefined data from the file for the range which is wrong. Then, press save. The jpg will now carry the correct preview image and you can now begin using FLIR Tools to add measurements or create a report.

I can see in the images and video that there's some vertical "stripe noise" that is static, you should be able to remove that with a "dark frame".
In form/location or/and intensity? Global intensity of individual noise pixels change?
Edit: I'm looking at mine (a CEM) and it has that "dark frame" too.
How do you mount the reversed lens?
Are you processed the images with a noise reduction like in your panorama workflow?
Compared with your first image, there are no stripes

I think, your LR 8 bit intermediate step is not the best solution
