Description
1/3″ 3.68mm F2.4 M12 Wide Angle Lens
Enhance your optical device architectures with this high-precision 1/3″ 3MP 3.68mm M12 wide-angle lens. Optimized to deliver pristine clarity on mainstream high-definition sensors such as the AR0330, this lens provides an expansive 107° diagonal field of view with a crisp 3-megapixel resolution. Built with a professional 5G+IR cut (5 All-Glass Elements + Infrared Cut Filter) optical design and an F2.4 aperture, it ensures high light transmission, uniform brightness distribution (R.I. >80%), and accurate color fidelity. Boasting a well-controlled geometric distortion of -25% and a customized Chief Ray Angle (C.R.A. <21°), it prevents pixel shading, making it an ideal choice for premium action cameras, security surveillance, and embedded machine vision systems.
Key Product Highlights
- 107° Wide-Angle Scene Coverage: Captures a spacious wide view (85°H / 54°V) to eliminate critical blind spots while keeping wide-area layouts well-proportioned.
- Low Geometric Distortion (-25%): Highly optimized for a wide-angle lens, suppressing the heavy barrel curvature common in fisheye lenses to ensure more linear and natural images.
- Tailored Low Chief Ray Angle (C.R.A. <21°): Perfectly matches the micro-lens structure of modern CMOS sensors like the AR0330, preventing edge vignetting and color crosstalk.
- High Relative Illumination (R.I. >80%): Guarantees uniform edge-to-edge sensor brightness, eliminating dark corners and delivering vibrant contrast across the entire frame.
- Resilient 5G All-Glass Structure: Built with 5 precision layers of premium optical glass, providing excellent thermal stability and total resistance to heat-induced focus drift.

Frequently Asked Questions
- Q: Why are the C.R.A. <21° and R.I. >80% metrics significant for my camera?
- A: A Chief Ray Angle (C.R.A.) under 21° ensures that light rays strike the sensor pixels smoothly without spilling over, which avoids color distortion. Combined with a High Relative Illumination (R.I.) of over 80%, it ensures that the corners of your video remain bright, uniform, and clear rather than dim and dark.
- Q: Is this 3.68mm lens fully compatible with the AR0330 sensor?
- A: Yes. The optics were specifically tuned to illuminate the active pixel area of 1/3″ arrays like the AR0330 sensor, achieving the exact 107° diagonal field of view with maximum optical efficiency.
- Q: What are the main benefits of the 5G all-glass structure over plastic alternatives?
- A: Glass optics maximize light transmission and scratch resistance. More importantly, they prevent “thermal drift” (de-focusing) when camera chips heat up during long recording sessions or when exposed to hot sunlight.
- Q: Does this lens include a filter for daytime color precision?
- A: Yes, it features an integrated IR cut filter (IRCF) that accurately filters out ambient infrared wavelengths during daytime shooting, ensuring vibrant, true-to-life images with zero pink tinting.
- Q: How do we calibrate the focus on this fixed-focal lens?
- A: Focus is set manually during your camera module’s assembly phase. The operator screws the lens into the M12 thread block while analyzing a live reference monitor. Once crisp focus at your target distance is established, it is locked using a locking ring or a drop of optical adhesive.
