Description
Enhance your optical system with this high-performance Megapixel 180° Fisheye M12 Lens. Engineered with a 1.8mm fixed focal length and a large 1/1.8″ image format, this lens delivers a seamless 180-degree panoramic view across diagonal, horizontal, and vertical planes. Featuring a premium 6G+IR cut filter construction and a bright F2.5 aperture, it ensures crystal-clear imaging while filtering out infrared interference for true-to-life daytime color. Whether you are developing CCTV surveillance, automotive surround-view setups, drone & UAV navigation, or machine vision systems, this compact wide-angle lens offers exceptional edge-to-edge brightness.
Product Highlights
- 180° Full-Hemisphere Coverage: Provides 180-degree viewing angles horizontally, vertically, and diagonally, eliminating blind spots entirely with a single camera module.
- High 65% Relative Illumination: Solves the common industry pain point of dark edges in fisheye lenses, delivering a bright, evenly lit image from the center to the periphery.
- Ultra-Compact 15.17mm TTL: Features an exceptionally short Total Track Length (TTL 15.17mm), making it one of the lowest-profile optics available for space-constrained enclosures.
- 6G Glass & Integrated IR Cut Filter: Employs a 6-layer precision glass structure with a built-in IR cut filter to achieve crisp resolution and block unwanted IR light for accurate color rendering.
- Industrial Manual Focus Stability: Supports Manual Focus adjustment via the standard M12x0.5 thread, allowing engineers to lock in the perfect focal plane for high-vibration applications.

Target Applications & Compatible Devices
Core Application Scenarios
This ultra-compact 180° fisheye M12 lens is purpose-built for high-density visual applications where maximizing situational awareness is critical. It serves as an excellent optical module for 360-degree ceiling CCTV dome cameras, workspace mapping, and institutional corridor monitoring. In the transit sector, it functions perfectly for ITS intelligent traffic monitoring and automotive surround-view camera systems, providing continuous perimeter tracking for larger commercial fleets. Furthermore, its ultra-short 15.17mm TTL and exceptional 65% relative illumination make it highly sought after for drone & UAV autonomous navigation, factory FA lens automation rigs, and robotic machine vision where capturing a wider field with low edge fading is mandatory.
Compatible Device List
- Large-Format Sensors: Optimized for high-end 1/1.8″ CMOS sensors while remaining fully backward compatible with 1/2″ and 1/2.8″ image formats.
- Security & CCTV Frameworks: Natively compatible with Hikvision, Dahua, and mainstream IoT panoramic dome housings without bracket adjustments.
- Embedded Vision Kits: Pairs easily with industrial-grade PCBA modules, Raspberry Pi HQ camera components, and NVIDIA Jetson developer setups.

Frequently Asked Questions
Q: What is the purpose of the built-in IR cut filter on this 1.8mm M12 lens?
A: The integrated IR cut filter blocks infrared light above 650nm. This prevents color distortion and pink tinting during daylight operation, ensuring highly accurate, lifelike color reproduction on your sensor.
Q: What does the 65% Relative Illumination (R.I.) value indicate?
A: R.I. measures the brightness at the edge of the image compared to the center. While standard ultra-wide lenses suffer from heavy vignetting (dark corners), this lens maintains 65% edge brightness, delivering clear forensic detail across the entire 180° field.
Q: Does this lens feature fixed focus or manual focus?
A: It is a fixed-focal lens (1.8mm), but it features Manual Focus mechanical adjustments. This means you can manually thread the lens into your M12 mount during installation to dial in the absolute sharpest focus plane for your sensor distance.
Q: Can I use this 1/1.8″ image format lens on a smaller 1/2.8″ sensor?
A: Yes, it is fully backward compatible. However, because a 1/2.8″ sensor crops the outer edges of the Φ5.0mm image circle, your resulting diagonal, horizontal, and vertical fields of view will be less than 180 degrees.
Q: How does the short 15.17mm TTL benefit my product design?
A: The ultra-short 15.17mm Total Track Length allows your overall camera housing to be incredibly thin and lightweight. This is ideal for wearable cameras, compact drone undercarriages, and sleek automotive blind-spot housings.
Q: Is this 6G lens suitable for outdoor weathering and industrial setups?
A: Absolutely. The 6G full glass construction prevents the focus shifting or image degrading that occurs with cheaper plastic alternatives when exposed to extreme sun heat or sub-zero conditions.
