Description
1/2.7″ & 1/3″ 3.6mm 3MP M12 Wide Angle Fixed Focal Lens
Optimize your high-definition imaging systems with this versatile 1/2.7″ and 1/3″ 3MP 3.6mm M12 wide-angle lens. Engineered to deliver crisp 3-megapixel resolution, this lens features an advanced 5G+IRCF (5 All-Glass Elements + Infrared Cut Filter) optical structure that effectively ensures long-term thermal stability and edge-to-edge sharpness. Boasting a sweeping 121° diagonal field of view on a 1/2.7″ sensor and a bright F2.5 aperture, it offers the perfect combination of expansive visual coverage, low distortion, and compact integration for next-generation smart home security, automotive recording, and light industrial machine vision.
Key Product Highlights
- 3MP High-Definition Sharpness:Precision-calibrated optics perfectly resolve fine graphical details across 3-megapixel image sensors, eliminating blur and pixel degradation.
- Dual-Sensor Adaptive Perspectives: Offers a sweeping 121° diagonal FOV on 1/2.7″ sensors (90°H / 65°V) and seamlessly scales to a focused 105° diagonal FOV on standard 1/3″ sensor arrays.
- Premium 5G All-Glass Elements: Built entirely with 5 layers of professional-grade optical glass to guarantee excellent light transmission and total immunity to thermal focal shift (heat drift).
- Controlled Geometric Distortion: Optically corrected to suppress barrel curvature, keeping distortion below -48% on 1/2.7″ sensors and under -36% on 1/3″ formats for more linear, natural views.
- Standard M12 Mechanical Mount: Features a regular M12x0.5 interface thread with a short 5.6mm Back Focal Length (B.F.L.), allowing ultra-compact profile mounting in tight spatial environments.

Applications & Device Compatibility
Core Application Scenarios
This 3MP M12 wide angle lens is a highly adaptable optical solution designed for mass-market hardware architectures requiring broad visual fields within space-restricted device shells. It serves as a premier core lens for smart video doorbells, smart home security cameras, and apartment entryway monitors, where capturing full-length human silhouettes at closer operational ranges is necessary. Thanks to its rugged 5G all-glass composition, it performs reliably in automotive front-facing dashcams, fleet cabin monitoring systems, and reversing camera kits exposed to harsh sun glare and vehicle vibrations. Furthermore, it easily retrofits into automated banking ATM kiosks, office attendance turnstiles, and entry-level industrial robotic navigation assemblies.

Frequently Asked Questions
- Q: What is the benefit of the dual 1/2.7″ and 1/3″ sensor formatting options?
- A: This lens is multi-sensor compliant. If you install it on a 1/2.7″ sensor, you get a wider 121° perspective. If you move it to a 1/3″ sensor, it crops the edge naturally to a 105° view, meaning hardware engineers can use one single lens SKU across multiple product models to save cost.
- Q: How does the 5G all-glass structure outclass plastic lenses?
- A: Plastic lenses are prone to warping under extreme temperatures, causing the camera feed to go out of focus (thermal defocusing). The 5G all-glass array guarantees unvarying physical shapes and focal plane consistency from hot summers to freezing winters.
- Q: Why are there two separate distortion values provided?
- A: Optical distortion increases as you move outward from the center of the lens. Since a 1/2.7″ sensor captures a physically wider field of view than a 1/3″ sensor, it sees further out into the lens edges where distortion peaks at <-48%, whereas the cropped 1/3″ view remains tighter and lower at <-36%.
- Q: Does this lens handle night-vision security workflows properly?
- A: Yes. The lens features an integrated IRCF (IR Cut Filter) that keeps daytime color capture looking vibrant and true-to-life. For night mode configurations, it allows exceptional transmission when combined with complementary external lighting systems.
- Q: How do operators calibrate the focus during device assembly?
- A: This is a fixed-focal lens with manually calibrated installation focus. The line operator simply threads the M12 lens into the module holder while checking a live reference monitor. Once peak sharpness at the target distance is reached, the lens position is locked with a thread-locking compound.
