When 'larger target area' is no longer a universal solution: optical design is returning to system level trade-offs
Copywriting: In recent years, the industry has been pursuing full frame and large image surfaces, but it is easy to overlook a fact - every inch the lens resolution approaches the diffraction limit, the sensitivity to assembly tolerances and temperature drift increases exponentially. What really widens the gap is often not the peak of the MTF curve, but finding the minimum compromise between thermal balance, stray light suppression, and mass production consistency. Optical design is never an isolated technical competition, but an honest response to physical boundaries.

The M12 lens has an outer thread diameter of only 12 mm and screws directly onto the camera mount on the mainboard. Its miniaturization is achieved through a small sensor and a simple structure. It has a fixed aperture and a limited back-focus adjustment range, and requires high assembly precision. It is commonly used in compact devices such as automotive, drone, and access-control systems, with advantages including a small size, light weight, and suitability for mass integration.
