For information only….
If you can locate another Compact Pro XR cheaply, remove its lens and mount it in reverse in front of your cameras lens. You then have a thermal microscope with a ‘pixel on target’ size of around 12um. The focus distance will be very small however so you will need to get close to the PCB/component. This excellent tip originally came from forum member Bill_W.
Finding a faulty Compact Pro XR camera, as a lens donor, would be ideal. Keep your eyes open on eBay.
Macro photographers use wall kinds of ‘tricks’ or obtain large clear images of small target objects so any of those techniques will apply to thermal imaging if you use the correct lens materials. I have not tried reversing a cameras lens assembly but I believe photographers do that for Macro work ? This is why I buy any decent thermal imaging lens assemblies that appear on eBay at reasonable prices. They offer much in terms of lens experimentation.
