Description
2.5mm M12 Wide Angle Lens
Unlock exceptional nighttime clarity and expansive situational awareness with our premium 3MP 2.5mm M12 Wide Angle Lens. Specially engineered for low-light optical environments, this lens breaks industry performance barriers by combining a rapid F1.8 large aperture with a panoramic 160° ultra-wide field of view. Built with a robust 6G all-glass structure, it minimizes thermal drift while optimizing ambient light gathering capacity for full-color imaging in near-dark conditions. Whether you are configuring an automotive surround-view system or deploying next-generation security networks, this high-definition fixed focal M12 lens delivers a broad, blind-spot-free perspective with uncompromised image crispness.
Key Product Highlights
- Starlight F1.8 Large Aperture: Captures significantly more light than standard F2.8 lenses, dramatically improving sensor sensitivity for vibrant, noise-free images in low-light and nighttime environments.
- 160° Panoramic Vision: Delivers expansive horizontal and diagonal coverage to eliminate blind spots, making it perfect for wide-angle security, smart dashcams, and automated navigation.
- True 3-Megapixel HD Clarity: Optimized for high-definition 3MP image sensors, providing sharp pixel-to-pixel resolution across the entire frame for seamless object tracking and facial identification.
- Robust 6G All-Glass Elements: Utilizes six premium precision-ground glass layers that ensure exceptional optical clarity, high light transmission, and superior resistance to harsh environmental weathering.

Application Scenarios & Compatible Devices
Target Applications & Industry Deployment
This fast-aperture 3MP fisheye lens is structurally optimized for starlight night vision and critical security surveillance where ambient lighting cannot be guaranteed. It serves as an excellent automotive lens for commercial fleet dashcams, driving recorders, and 360-degree around-view monitoring (AVM) systems, allowing vehicles to register cross-traffic lanes seamlessly even at night. For smart urban infrastructure, it functions perfectly as an ITS lens or CCTV lens inside low-profile dome cameras at dark alleyways, automated parking garages, and entryway access portals. Additionally, its tight 22.5mm T.T.L. profile and clear close-up focus of 0.2m allow for smooth deployment as a machine vision lens or FA lens on autonomous warehouse robots requiring continuous visual navigation under varied factory lighting.
Hardware Compatibility List
- Sensor Compatibility: Built precisely for 1/2.7″ format image sensors, serving as an ideal optical match for the high-sensitivity Sony IMX462, IMX327, and Omnivision OV2710.
- Automotive Dashcams: Seamlessly integrates with AI-driven electronic mirrors, advanced driver assistance systems (ADAS), and dual-lens taxi cabin monitors.
- Security Camera Modules: Direct drop-in compatibility with low-illumination S-mount (M12) IP camera boards from Hikvision, Dahua, and Tuya ecosystem hardware.
- Edge AI Vision Kits: Fully compatible with compact development kits like NVIDIA Jetson Nano or Raspberry Pi camera setups requiring full-panoramic low-light input.
“Designed for starlight night-vision surveillance and automotive surround-view applications.”
Frequently Asked Questions
- Q: Does this 2.5mm lens support night vision?A: Yes, with its ultra-large F1.8 aperture, this lens acts as a premium starlight night-vision lens, gathering substantial ambient light to provide clear and vibrant color imagery even under extremely low-light night conditions.
- Q: Will this lens fit a standard 1/3-inch or 1/2.8-inch sensor?A: Absolutely. The lens supports up to a 1/2.7″ image format, which means it will fully cover and perform exceptionally well on smaller 1/2.8″ (like Sony IMX462) and 1/3″ sensors without any corner vignetting or dark edges.
- Q: Why does the image look bent or curved?A: This is a characteristic feature of an ultra-wide fisheye lens. The <-78% optical barrel distortion is essential to capture the massive 153° to 160° field of view. This distortion can easily be corrected via digital dewarping software on the backend if straight lines are required.
- Q: Does this lens contain plastic elements inside?A: No, this lens uses a strict 6G (6 All-Glass) optical construction. Glass elements provide far superior light transmission and prevent the focus from shifting or blurring due to temperature changes in outdoor environments.
- Q: Can I use this lens for short-range industrial inspection?A: Yes, the lens features a Minimum Object Distance (M.O.D.) of 0.2 meters (approx. 7.8 inches), allowing objects placed near the lens to stay completely sharp and in focus, ideal for compact automation setups.
- Q: Is the iris adjustable for bright sunlight conditions?A: This lens is a Fixed Iris model set at F1.8. To manage lighting in extreme daytime environments, your camera module should utilize electronic shutter speed control or automatic digital gain.
