Target Applications & Compatible Devices
Core Application Scenes
This 4.0mm low distortion M12 lens is purpose-built for high-accuracy automated vision sectors where shape deformation cannot be tolerated. It excels in factory automation (FA) lines for multi-code reading, automated sorting, and robot-guided assembly. Thanks to its balanced 86° wide field of view, compact 22mm TTL, and 0.1m macro focus, it is highly effective in handheld medical endoscopy devices, biometric scanners, and smart parcel locker cameras. Furthermore, its rugged 2G2P hybrid build guarantees thermal stability under intense vibrations, making it an ideal choice for automotive front-facing dashcams, rear-view backup cameras, and industrial surveillance systems.

Frequently Asked Questions
Q: Why is a <-0.4% optical distortion rating important for machine vision?
A: Standard lenses warp lines near the edges into curves. A distortion rating under 0.4% ensures pixels correspond perfectly to real-world dimensions, eliminating the need for heavy digital correction during robotic measurements.
Q: Does this lens include an IR-cut filter by default?
A: Yes, the lens features a built-in IR cut filter (2G2P+IR cut) to filter out infrared light during daylight operations, preventing color shifts and keeping contrast sharp.
Q: What is the benefit of the F2.8 fixed aperture?
A: The F2.8 aperture provides a perfect balance. It lets in ample light for low-light tracking while maintaining a wide depth of field so moving parts stay in focus.
Q: Can I use this M12 lens on a camera with a smaller 1/3″ sensor?
A: Yes, it is fully backward compatible with 1/2.8″ and 1/3″ sensors. Note that a smaller sensor will slightly narrow the overall horizontal field of view.
Q: What does the 0.1m Minimum Object Distance (M.O.D.) allow me to do?
A: It allows the camera to focus sharply on targets just 10cm away from the lens tip, making it ideal for macro component inspection and close-up medical diagnostics.
Q: Is this lens compliant with international environmental standards?
A: Yes. This lens is manufactured under strict ISO9001 guidelines and is fully certified by RoHS, meeting all EU security and environmental access criteria.
