You certainly wouldn’t want to look for this camera on the ground.

Due to its dimensions, this camera is of course primarily intended for specific applications in surgery and in areas such as neurology, ophthalmology, ENT, cardiology, urology, gynecology or arthroscopy. Surgeons with it have such a miniature device that it can fit into even the smallest veins inside the human body. But it can also be used in the Internet of Things or wearable devices. The manufacturer guarantees its functionality from minus 20 ° C to plus 70 ° C.

There are very few cameras that can approach the OmniVision OV6948, they often also have a much lower resolution and poor frame rate. However, OmniVision captures an image at 30 frames per second and can have analog output over 4 meters with minimal noise. The camera also has a field of view with a 120-degree angle of view, which would mean 14 nm on a full-frame sensor with a conventional camera. The depth of field is between 3 and 30 mm. For its miniature size, it was also entered in the Guinness Book of Records. Find out more on the OmniVision website.
