The camera is working well, now. There were some initial teething troubles with the software and it needed a much more powerful phone than I'd got (I'm now using a Samsung S7) but the images from it are very nice. Here's a small selection:
This is of course a stitched panorama -
larger versions are here. The original is 6421x2886, 18 megapixels, which you should be able to download from Flickr and explore at your leisure.
and finally
a high definition video of the Spain-Gibraltar border area and Gibraltar airport.
There are some more sample images here.The Therm-App Pro camera is indeed only available to special order at present; you'll need to contact Opgal sales. I understand they are built to order, rather than being a stock item. The Therm-App Pro costs something like US$3000 (or maybe more, depending on lens), possibly plus delivery, likely plus import taxes and duty etc. As far as I know it's one of the least expensive 25Hz 640x480 imagers available and, at <30mK, it claims the lowest NETD (best sensitivity) of almost anything 640x480 this side of cooled sensors, at any price. (For comparison, the regular Therm-App says <70mK; the ThermalExpert 384x288 and 640x480 both say <50mK). Take all these figures with a pinch of salt, of course, because they strongly depend on the lens used, but all the Therm-Apps use the same range of lenses
* and the lenses on the ThermalExpert cameras seem very, very similar.
* The 6.8mm lens (which works fine on the 384x288 Therm-App) vignettes significantly on the 640x480 Therm-App Pro. There is very slight vignetting on the 13mm lens. Opgal only offers the Pro with the 19mm or 35mm lenses, both of which work fine on either camera.
