Description
1/3″ 2.3mm 4MP F2.2 M12 Ultra-Wide Angle Fisheye Lens
Expand your imaging boundaries with our professional 1/3″ 4MP 2.3mm M12 ultra-wide angle fisheye lens. Meticulously engineered for 4-megapixel (2K Full HD) sensors, this lens captures a sweeping 172° diagonal perspective to ensure absolute scene awareness. Featuring an advanced 6G+IRCF (6 All-Glass Elements + Infrared Cut Filter) optical design and a bright F2.2 aperture, it delivers edge-to-edge sharpness and pristine color accuracy while remaining completely immune to thermal focus drift. With its ultra-compact frame and an impressive 0.1m Minimum Object Distance, it stands as the premier optical solution for panoramic surveillance, automotive intelligent vision, and compact AI hardware.
Key Product Highlights
- 172° Ultra-Wide Panoramic View: Delivers an immersive panoramic field of view (127°H / 92°V) on 1/3″ sensors, effectively eliminating critical visual blind spots with a single camera module.
- 4MP Ultra-HD Resolving Power: Precision-optimized optics match high-density 4-megapixel sensor matrices, extracting crisp textures and sharp geometries for intelligent backend analytics.
- Resilient 6G All-Glass Structure: Built entirely with 6 layers of professional optical glass, maintaining an invariant focal plane under tough sunlight and extreme outdoor temperature changes.
- 0.1m Micro Focusing Capabilities: Boasts an exceptionally short Minimum Object Distance (M.O.D.) of just 0.1m, bringing ultra-close objects and macro scans into flawless, precise focus.
- Optimized Distortion Profile: Controls horizontal geometric distortion down to <-41% (H), a highly refined optical engineering feat for an ultra-wide panoramic lens close to 180 degrees.

Applications & Device Compatibility
Core Application Scenarios
This 4MP M12 fisheye lens is intentionally crafted for electronic hardware applications that require sweeping spatial orientation and crisp, ultra-high-definition video data streams. It acts as an optimal optical component for automotive 360° surround-view monitoring systems (AVM), fleet front-facing dashcams, and rearview cameras where rugged environmental resistance is expected. Thanks to its lightweight profile and ultra-wide view, it excels within commercial drone navigation, UAV mapping, and AGV robotic situational awareness platforms for seamless real-time obstacle avoidance. Furthermore, it delivers top-tier performance in commercial panoramic security, such as single-lens 360° ceiling-mounted domes for retail shops, smart parking structures, and residential video doorbells.

Frequently Asked Questions
- Q: What are the main benefits of the 6G all-glass structure on this fisheye lens?
- A: All-glass optics maximize light throughput and resist superficial scratches. More importantly, they prevent “thermal drift” (de-focusing) when camera modules run continuously or are deployed outdoors under direct summer sun glare.
- Q: Can this 1/3″ lens fit smaller image sensors?
- A: Yes, it can be mounted on 1/4″ sensor arrays. While it is fully compatible, please note that the field of view will crop proportionally, yielding a narrower viewing angle than 172° while retaining sharp optical clarity.
- Q: How does the <-41% horizontal distortion affect my image?
- A: For a lens approaching a full 180° view, keeping horizontal distortion under 41% is an exceptional engineering design. It creates an immersive panoramic overview, and the barrel warping can easily be flattened out via backend camera dewarping software algorithms if a linear view is required.
- Q: Does this lens include a filter for precise color rendering?
- A: Yes, it contains a built-in fixed IRCF (IR Cut Filter) that accurately filters out ambient infrared wavelengths during daytime shooting, ensuring vibrant, true-to-life images with zero pink tinting.
- Q: How do we calibrate the focus on this fixed-focal M12 lens?
- A: Focus is set manually during your camera module’s assembly phase. The technician screws the lens into the M12 thread block while analyzing a live reference monitor. Once crisp focus at your target distance is established, it is locked using a locking ring or optical adhesive.
