In the realm of underwater exploration and inspection, the clarity and precision of visual data are paramount. The right optical tools are crucial for scientific research, marine archaeology, and maintaining offshore infrastructure. Enter M12 lenses for underwater inspection – a game-changer in the world of subaqueous imaging.
M12 Lenses for Underwater Inspection: A Closer Look
Understanding M12 Lenses
M12 lenses, also known as S-mount lenses, are characterized by their M12X0.5 thread, allowing them to be directly threaded into the M12 mount of a PCB (Printed Circuit Board) camera. This design, often referred to as a “board lens” or “miniature lens,” makes them incredibly compact and versatile. Their compact size boosts performance in space-constrained settings like underwater drones and ROVs.
