$40 Lens Hack Gives Your FLIR Higher Clarity

flirHack

[Josh Oster-Morris's] FLIR camera can see a bit more clearly now that he’s hacked it to have its own makeshift “macro” mode. You may remember [Josh] from his power distribution Motobrain project. He’s still improving the Motobrain, and he wanted to better understand the thermal characteristics of the high current draws (upwards of 100amps!)

After reading that the FLIR 4  could be hacked into a better version, [Josh] immediately purchased his own. The FLIR is, however, limited at close-range imaging, because the resolution of the FLIR’s microbolometer is relatively low.  He had fortunately decided to stay tuned in to [Mike's] YouTube channel and saw his follow-up video a few days later on refocusing the FLIR camera with an external lens. [Josh] hit up Amazon for a Gallium Arsenide lens normally used for CO2 lasers, and found one for around $40. He then mounted this lens into a simple paper frame held together by tape and staples, and fitted it onto the FLIR.

After you’ve checked out [Josh's] blog for more examples of how astoundingly clear the images become, check out [Mike's] video detailing the hack below.
