Description
This professional-grade 5-Megapixel Low Distortion Lens is engineered for high-precision imaging, featuring a 4.0mm fixed focal length and a sophisticated 2G2P+IRF optical structure. Designed with a standard M12 mount, it serves as a premier choice among M12 Lenses for applications requiring extreme geometric accuracy. With an ultra-low distortion rating of less than -0.4%, it is a top-tier Machine Vision Lens and Industrial Lens solution for developers who demand clarity without the “fisheye” warp.
Scenario-Based Functional Descriptions
Ultra-Low Distortion for Precision Machine Vision:
Boasting a distortion rate of <-0.4%, this lens ensures that straight lines stay straight. In the realm of Machine Vision Lens applications—such as OCR (Optical Character Recognition), barcode scanning, and industrial dimension measurement—this precision eliminates the need for heavy software-side dewarping, saving processing power and improving accuracy in FA lens (Factory Automation) environments.
5MP High-Resolution Clarity for AI Perception:
Optimized for 1/2.3″ sensors, this 5MP lens delivers crisp, high-definition imagery. Whether integrated into a CCTV Lens assembly for smart security or used as an Industrial Lens for quality inspection, the 4.0mm focal length provides a balanced 75°(H) field of view, capturing detailed textures and fine edges essential for AI-driven object recognition.
Industrial-Grade Compact Integration:
With a Total Track Length (TTL) of only 21.98mm and a compact Φ14mm diameter, this M12 Lens is purpose-built for space-constrained hardware. Its lightweight yet durable construction makes it an ideal Fixed Focal Lens for drone payloads, handheld scanners, and compact medical imaging devices where every millimeter counts.
Optimized Optical Performance (F2.8 & IRCF):
The F2.8 aperture strikes a perfect balance between depth of field and light throughput. Combined with an integrated Infrared Cut-off Filter (IRF), this lens ensures true-to-life color reproduction by blocking infrared interference, making it a reliable CCTV Lens for daytime surveillance and high-accuracy color sorting in industrial lines.

FAQs
Q: What makes this lens “Low Distortion” compared to standard wide-angle lenses?
A: Most wide-angle M12 Lenses have a TV distortion of 5% to 20%, causing images to curve at the edges. Our lens reduces this to <-0.4%, meaning the image captured is almost perfectly identical to the real-world scene, which is critical for Industrial Lens applications.
Q: Is this lens compatible with standard 1/2.3″ or 1/3″ sensors?
A: Yes. While optimized for 1/2.3″ formats to utilize the full 5MP resolution, it is backward compatible with smaller sensors like 1/2.5″ and 1/3″, offering a slightly narrower FOV without any vignetting.
Q: Does this lens include an IR filter?
A: Yes, the 2G2P+IRF structure includes a built-in Infrared Cut-off Filter (650nm). This ensures accurate color rendering under natural light, making it a “plug-and-play” CCTV Lens solution for daytime monitoring.
Q: Can this lens be used for automated warehouse robotics (AMR)?
A: Absolutely. The combination of Fixed Focal Lens stability, 5MP resolution, and low distortion makes it perfect for visual SLAM, floor-marker navigation, and obstacle detection in robotic systems.
