Description
1/3″ 2.1mm M12 Ultra-Wide Angle Fisheye Lens
Expand your visual horizons with our professional 1/3″ 3MP 2.1mm M12 ultra-wide angle fisheye lens. Meticulously engineered for 3-megapixel (2K scaling) sensor architectures, this lens captures a sweeping 160° diagonal perspective to provide comprehensive 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 contrast and true-to-life color fidelity while remaining completely immune to thermal focus drift. With its compact 22.50mm Total Track Length (T.T.L.), it stands as a premium optical solution for panoramic surveillance, automotive intelligent vision, and compact AI hardware.
Key Product Highlights
- 160° Sweeping Panoramic View: Delivers an immersive panoramic field of view (123°H / 90°V) on 1/3″ sensors, effectively eliminating critical visual blind spots with a single camera module.
- 3MP High-Definition Resolving Power: Precision-optimized optics match high-density 3-megapixel image sensors, capturing sharp details and fine textures for intelligent backend analytics.
- Resilient 6G All-Glass Structure: Built entirely with 6 precision layers of optical glass, maintaining an invariant focal plane under tough sunlight and extreme outdoor temperature changes.
- Optimized Distortion Profile: Controls horizontal geometric distortion down to <-39% (H), a highly refined optical engineering milestone for an ultra-wide panoramic lens close to 160 degrees.
- Standard M12 Threaded Mount: Classic M12x0.5 interface with a short Total Track Length (T.T.L.) of 22.50mm, enabling seamless, low-profile hardware integration into space-constrained shells.

Applications & Device Compatibility
Core Application Scenarios
This 3MP M12 fisheye lens is intentionally crafted for electronic hardware applications requiring sweeping spatial orientation and crisp, high-definition video data streams. It acts as an optimal optical component for automotive front-facing dashcams, rearview backing cameras, and 360° surround-view fleet monitoring setups where rugged environmental resistance is required. Thanks to its lightweight profile and ultra-wide view, it excels within commercial mapping drones, UAV navigation networks, and autonomous AGV robotics for seamless real-time obstacle avoidance in warehouse aisles. Furthermore, it delivers top-tier performance in commercial panoramic security, such as single-lens ceiling-mounted domes for retail shops, smart parking structures, and residential smart video doorbells.
Compatible Device List
- Sensors: Optimized for standard 1/3″ high-resolution CMOS sensor arrays (e.g., Sony, OmniVision, Onsemi series) and backward compatible with smaller 1/4″ formats.
- Automotive Tech: Seamlessly integrates into car DVR systems, commercial truck telematics enclosures, and standard backing camera hardware assemblies.
- Drones & Robotics: Fits professional FPV quadcopter camera modules, autonomous mobile robots (AMRs), warehouse sorting AGVs, and drone sensor payloads.

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 160° while retaining sharp optical clarity.
- Q: How does the <-39% horizontal distortion affect my image?A: For a lens approaching a full 160° view, keeping horizontal distortion under 39% 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.
