- Automotive Modules: Seamlessly integrates with vehicle rear-view cameras and surrounding-view monitor (SVM) systems.
- Smart Security & IoT: Enhances premium biometrics, facial recognition terminals, and high-end smart video doorbells.
- Embedded Vision Systems: Perfect for Raspberry Pi, Jetson Nano camera modules, and custom drone/UAV mapping payloads.
Designed for high-precision machine vision and rugged automotive applications.
Frequently Asked Questions
Q: Can this 8MP M12 lens be used on a sensor smaller than 1/2.5″?
A: Yes, it is fully backward compatible with smaller sensor sizes such as 1/2.7″, 1/2.8″, and 1/3″. Please note that using a smaller sensor will narrow the final field of view (F.O.V.).
Q: What does the “<-0.4% Distortion” mean for my image quality?
A: This indicates an ultra-low distortion optical design. Images will have virtually zero noticeable barrel or pincushion warping, allowing your software to perform precise measurements without digital geometric correction.
Q: Does this lens feature an integrated IR cut filter?
A: Yes, the lens comes built-in with an IR cut filter (650nm standard) to block infrared interference during daylight, ensuring accurate and vivid color reproduction.
Q: Is the 3G2P construction suitable for outdoor automotive environments?
A: Absolutely. The 3 Glass and 2 Plastic element hybrid configuration provides excellent thermal stability, preventing focus shift or image degradation when exposed to extreme outdoor temperatures.
Q: Can I request a customization for the IR filter or mechanical dimensions?
A: Yes, we offer tailored optical solutions. We can customize the IR filter coatings (e.g., dual-band or specific bandpasses) and modify mechanical mounts to meet your hardware requirements.
Q: What is the benefit of the 0.1m M.O.D. (Minimum Object Distance)?
A: It allows the camera to focus on objects as close as 10 cm away from the lens. This is critical for compact medical devices, close-range barcode scanners, and robotic components inspection.
