About this item

The Arducam M40180H13L is a precision-engineered M12 mount camera lens designed for use with various embedded camera systems such as Raspberry Pi, Arduino, and USB camera modules. Offering a 4mm focal length and a horizontal 180-degree field of view, this fisheye lens is ideal for applications that demand ultra-wide-angle imaging and panoramic coverage. Built for versatility, the lens is compatible with M12 lens holders and sensors ranging from 1/2.5" to 1/4" optical formats. Its compact form factor makes it suitable for space-constrained projects like drones, robotics, 360-degree surveillance, and AI vision systems. The fisheye distortion is intentionally designed to maximize scene capture in a single frame, making it perfect for monitoring large areas without needing multiple cameras. Constructed with multi-element glass optics, the lens ensures sharp image quality, high light transmission, and durability over extended use. The M40180H13L also features an IR-cut filter (or optional NoIR variant) for true-to-life daytime color reproduction. Whether you're developing an autonomous navigation system or setting up an ultra-wide-angle security camera, this Arducam M12 lens delivers expansive views with dependable optical performance in a miniature, lightweight package.
