Make Your Cheap Thermal Camera into a Microscope

In a fascinating DIY project, [Project 326] has managed to transform a humble, cheap thermal camera into a high-resolution microscope with a magnification measured in microns.

The idea may seem far-fetched, but it's actually quite straightforward. The project begins with the use of a smart phone-compatible thermal camera that plugs into the device itself. While these cameras are undoubtedly handy, their limitations become apparent when trying to achieve high-resolution imaging.

One of the primary challenges facing microscopes is the transmission of IR radiation through glass lenses. Germanium, an exotic material, offers a promising solution to this problem. By incorporating a single germanium lens into the setup, some magnification can be achieved. However, as [Project 326] demonstrates, using a 3D printed holder with three lenses in play yields truly impressive results.

The resolution of the microscope is so sharp that it allows us to see the subtle turns of wire within an incandescent light bulb. Moreover, imaging heat at such high resolutions provides valuable insights into various materials and phenomena. The video showcasing this project will surely leave viewers amazed and inspired.

In a tantalizing hint at what's to come, [Project 326] teases the possibility of building an IR telescope using first surface mirrors. This ambitious endeavor has the potential to be adapted to work with a wide range of IR cameras, making it accessible to a broad audience.

For those interested in exploring this project further, the thermal camera module used in the video is the UNI-T UTi-260M, which can be obtained for approximately $400. The total cost of the build itself comes out to around $35.

One thing's certain: IR imaging has the power to reveal incredible secrets about the world around us. Whether it's examining intricate circuitry or gazing into the heart of an IC, this technology holds immense promise for scientists and DIY enthusiasts alike.
