This is India's first germanium-free thermal imaging system for drones. It was built right here in India by this Hyderabad-based startup -
@EonSpacelabs.
And it is a huge deal.
Right now, India imports almost 100% of its germanium. No points for guessing which country controls the germanium supply chain (yup, it's China).
Now, building the lens is great. But that was only part of the solution. See, surveillance drones equipped with these EON Space Labs' imaging systems might get deployed in Kashmir's -20 degrees Celsius temperature or hot desserts of Rajasthan where temperatures can reach nearly 50 degrees Celsius. And in those conditions - lenses can either contract or expand slightly. But that slight change can hamper its ability to distinguish a rock from a human from a 2km distance - which can be critical.
To fix this - EON Space Labs has trained their AI which takes into account things like heat intensity, along with spatial and temporal recognition patterns. Oh and btw - they've also built India's lightest space telescope called MIRA - which weighs just 500 gms and has the ability to capture and process the image in space - instead of sending it back on Earth.
