1/1.8" 5MP Low Distortion M12 8mm Industrial Lens-Jinyuan

This 8 mm fixed-focus M12 lens is specifically engineered for 1/1.8-inch large-format image sensors, enabling native 5-megapixel resolution imaging with an ultra-low-distortion optical architecture. The design effectively suppresses geometric distortion—such as barrel and pincushion aberrations—ensuring high edge-to-edge sharpness, consistent modulation transfer function (MTF) performance, and faithful spatial fidelity across the entire field of view. These characteristics meet stringent requirements for precision machine vision, automated optical inspection, and high-accuracy surveillance applications.

The lens incorporates a proprietary multi-layer anti-reflection (AR) coating optimized for broadband spectral transmission (400–900 nm). This significantly mitigates stray light, ghosting, and veiling glare under challenging illumination conditions—including mixed indoor/outdoor lighting and high-contrast scenes—thereby enhancing contrast ratio, color accuracy, and low-light visibility without compromising signal-to-noise ratio.

With a focal length of 8 mm and a well-balanced horizontal field of view (51.8° on 1/1.8″ sensor), the lens achieves an optimal trade-off between working distance, depth of field, and spatial sampling density—making it particularly suited for medium-range industrial imaging, embedded vision systems, and AI-powered visual perception tasks.

Mechanically, the lens features a standardized M12×0.5 metric thread mount, compact form factor (≤22 mm total length), and robust mechanical construction with tight tolerance control (±0.02 mm axial positioning repeatability). Its modular design ensures seamless integration into space-constrained camera modules and supports long-term operational stability under thermal cycling (−20 °C to +60 °C) and vibration environments.
