Target Applications & Compatible Devices
Core Application Scenes
This ultra-wide M12 fisheye lens is built for extreme panoramic viewing where massive spatial data needs to be packed onto a compact sensor. It serves as an excellent optical module for smart asset tracking, commercial drone/UAV aerial Mapping, and sweeping dashboard cameras. Thanks to its low-profile 21.60mm TTL housing and premium 5MP resolution, it is highly effective in modern automated logistics warehouses for AGV automated guided vehicles, ceiling-mounted 360° office dome cameras, and close-proximity industrial inspection cells where wide coverage is demanded from short working distances.
Compatible Device List
- Sensors: Tailored for 1/4″ format CMOS imaging sensors (supporting image circles up to Φ4.6mm).
- Hardware Platforms: Fully fits standard M12 thread camera boards, embedded ARM/Raspberry Pi industrial modules, and Tuya ecosystem smart appliances.
- Integrated Devices: Compatible with high-end panoramic security domes, drone flight controllers, automotive backup displays, and wide-angle face-recognition kiosks.
- Optical Customization: Supports specialized configurations for anti-reflection coatings and varied IR cut wavelengths based on specific client design requirements.
“Designed for panoramic machine vision and ultra-wide drone navigation applications.”
Frequently Asked Questions
Q: Can this 5MP lens be installed on a 1/3″ sensor?
A: This lens is precision-optimized for a 1/4″ sensor format with a Φ4.6mm image circle. Installing it onto a larger 1/3″ sensor may create significant black corner clipping (vignetting).
Q: What is the main advantage of the <75% distortion spec?
A: For a 198-degree wide angle lens, keeping distortion below 75% is an exceptional engineering design. It means the fish-eye optical compression curve is highly predictable, making it significantly easier for your software algorithms to de-warp into a natural flat projection.
Q: Is the focus mechanism adjustable or locked permanently?
A: The lens features a manual focus design. You thread the lens into your M12 mount to achieve the perfect focal distance, then secure it using a standard M12 locking ring to prevent focus shift.
Q: How does the 6G optics composition benefit outdoor surveillance?
A: The 6G moniker signifies 6 layers of premium all-glass elements. Unlike plastic lenses which warp, yellow, or drift out of focus when exposed to direct summer sunlight, all-glass lenses maintain perfect focal alignment across extreme outdoor temperatures.
Q: Does this M12 lens support day/night dual-pass infrared setups?
A: This specific variant includes an integrated IR-cut filter to maximize daytime color fidelity. If your project requires 850nm or 940nm night-vision passability, please contact us for our non-IR filter variant.
