I would say you should buy the FLIR One I'm selling on
ebay...With the left over money I would buy
1. A ZnSe lens with around 50 mm focal length for closeup work [20Eur]
2. One or two ZnSe ND filters [around 200Eur, or does anybody know a cheaper source?]
3. The new 1.99 Eur iPhone App that gives the full sensor resolution
So for 440 Eur you get a setup with which you can image almost arbitrarily high temperatures,
like thousands of degrees and very small features. Much 'hotter' than 330C in my opinion...
By the way, and a little off topic, did anybody ever try to unscrew the lepton sensor lens for better close distance focus?
Is there any appreciable space between the shutter and the lens so it would fit back on?
