Description
Eliminate blind spots and achieve full environmental awareness with our premium 5MP 1.4mm M12 fixed focal lens. Specifically optimized for large 1/2″ image sensors (Φ4.7mm image circle), this high-performance fisheye lens delivers an ultra-wide, spherical 185° field of view horizontally, vertically, and diagonally. Featuring a bright F2.0 aperture and a precise F-theta linear projection layout, it captures crisp 5 Megapixel situational detail right to the image edges. It is the ultimate optical solution for international hardware teams building next-generation automotive lens systems (360° AVM), panoramic CCTV lens modules, and autonomous drone & UAV lenses.
Product Highlights
- Complete 185° Surround View: Captures a seamless spherical field of view across all axes, replacing multiple traditional cameras with a single central sensor to radically lower hardware costs.
- Optimized 1/2″ Large Sensor Format: Accommodates high-density 1/2″ formats without clipping, providing maximum light gathering and improved peripheral pixel mapping compared to tiny mobile optics.
- Fast F2.0 Aperture Performance: Draws in massive light volumes for nighttime clarity, ensuring sharp, noise-free security mapping and obstacle recognition in dimly lit conditions.
- Linear F-θ Distortion Architecture: Controls standard fish-eye warping to a predictable F-theta profile (<-3.7%), providing mathematically uniform pixels that simplify edge de-warping algorithms.

Target Applications & Device Compatibility
Core Application Scenarios
This 185° wide angle lens is custom-designed for spherical surround-view systems and hemispherical security surveillance. It serves as the core optical component for automotive Around View Monitoring (AVM), providing 360-degree blind-spot coverage for large commercial trucks, delivery fleets, and autonomous vehicles. Its comprehensive 185° perspective makes it exceptional for single-camera ceiling mount ceiling surveillance in retail warehouses, open-space parking structures, and public transit interiors. Additionally, it offers invaluable blind-spot coverage for smart drone & UAV lenses, industrial robot spatial navigation, and immersive VR/AR panoramic field stitching arrays.
Compatible Device List
- Sensors & Core CMOS Blocks: Fully optimized for high-end 1/2″, 1/2.5″, and 1/2.8″ sensors (such as mainstream Sony IMX global shutter or Onsemi NIR-enhanced 5MP chips).
- Automotive Surround Systems: Integrates smoothly into side-mirror pods, front grille housings, and rear-view backup cameras for commercial multi-camera stitching boxes.
- Security & Industrial Hardware: Fits standard 360-degree dome cameras, panoramic IP CCTV lens bases, and customized machine vision inspection hubs.
- Customization Services: Supports volume modifications for specific optical band coatings (e.g., dual-band pass filters), hardened glass outer elements for weatherproofing, or adjusted mechanical threads.
Designed for 360° automotive surround-view and panoramic security applications.
Frequently Asked Questions
Q1: What is an F‑theta lens design and its benefit for the fisheye lens?
A: Unlike regular distorted‑projection lenses, F‑theta yields uniform pixel density over the 185° view, simplifying AI video processing.
Q2: Does the 1/2‑inch lens fit 1/3″ or 1/2.8″ smaller sensors?
A: It works yet crops the image circle, losing the full 185° panoramic field‑of‑view.
Q3: Can the outermost glass withstand outdoor harsh conditions?
A: Its scratch‑resistant front optical glass suits outdoors; IP67/IP69K sealed housing is advised for tough scenarios.
Q4: How to focus this manual‑focus M12 lens?
A: Screw the M12×0.5 lens in, twist the barrel for sharpness on live feed and fasten it with locking parts.
Q5: Is the lens compatible with 850nm & 940nm IR night‑vision lights?
A: Stock versions carry an IR‑cut filter; bulk‑order units are available with customized IR‑coating or no IR‑cut filter.
Q6: Are MTF curves and compliance documents available for tender requests?
A: Our ISO9001‑certified factory supplies RoHS‑related full‑set technical files for overseas product validation.
