A YouTuber has shown how a cheap thermal imaging camera can be used as a microscope, modifying it to achieve a resolution of just a few microns.
While single germanium lenses offer some magnification, using three lenses held in a 3D-printed holder allowed for much greater magnification.
The camera used in the experiment was the UNI-T UTi-260M, which costs around 400,withthebuildcostingaround35 additionally.
The YouTuber teases that the technique could be used to create an infrared telescope using first-surface mirrors.
Alternatives to the UNI-T UTi-260M thermal imaging camera include the Flir One Pro and the Seek Compact PRO, both of which are considerably more pricey than the UNI-T.
