CCL14040MPFR

Description

This 4mm 5MP low distortion M12 fixed focal wide-angle industrial lens is engineered with a 2G2P optical structure matched with an IR cut filter, tailored for 1/4” image sensors. Featuring ultra-low distortion under -0.4%, fixed F2.8 aperture and 0.2m minimum object distance, the lens delivers sharp, uniform imaging across the entire image plane. Compact Φ14×18.7mm mini size fits narrow assembly space of miniature cameras, smart monitoring equipment and machine vision modules. Strict optical calibration and standardized M12 mounting greatly reduce assembly difficulty while stabilizing long-term imaging performance for continuous industrial and security monitoring operations.

Key Product Highlights

Field of View & Focal Length Advantages

4.0mm fixed focal length paired with 60° diagonal wide field of view covers larger monitoring areas without blind zones, solving narrow shooting range defects of ordinary short focal lenses. Horizontal 49.5° & vertical 38° viewing angles realize proportional distortion-free picture framing for square/rectangular CMOS sensors.

Premium Imaging Performance

Adopts 2G2P full-glass optical lens group plus built-in IR cut filter, realizes accurate visible light filtering and IR correction; maximum distortion less than -0.4% eliminates image edge stretching and deformation. 5MP high resolution matches mainstream megapixel sensors for clear detail restoration.

Strong Universal Compatibility

Standard M12×0.5 threaded mount matches most mainstream board cameras; tiny Φ14×18.7mm body adapts compact device shell design. Fixed F2.8 aperture guarantees stable light intake in low-brightness indoor & semi-outdoor environments.

Strict Reliability Quality Assurance

Total track length controlled at 21.98mm with fixed iris structure avoiding aperture failure during long-time operation; MOD as short as 0.2m supports close-range object capture. Mass production follows unified optical testing standards to reduce individual imaging differences.

Detailed Product Parameter

This product is RoHS certified, ISO9001 quality control certified, supports third-party testing, and complies with EU/domestic security equipment access standards, alleviating customer quality concerns.

Product Application Scenarios and Compatible Devices

Core Application Scenarios

This low-distortion M12 4mm wide-angle lens is mainly deployed for indoor small-scale CCTV surveillance, miniature machine vision detection, smart doorbell cameras, warehouse mini monitoring probes, consumer IoT security cameras, small industrial code reading modules, equipment internal visual inspection and low-speed logistics conveyor surface detection. The ultra-small overall dimension is perfectly adapted to compact camera module shell design, no extra structural modification is required during installation to shorten product assembly cycle. The 0.2m short MOD supports close-distance shooting for component surface flaw inspection, while the IR cut structure ensures true color restoration in daytime monitoring without color cast. Low distortion property prevents distorted identification of barcode and workpiece outline in machine vision scenes, effectively lowering error rate of visual recognition equipment under long-running working conditions both indoor and sheltered outdoor environments.

Compatible Devices List

Fully compatible with all mainstream 1/4-inch CMOS image sensors on the market. Matches Tuya smart IoT camera modules, mini network surveillance cameras, smart video doorbell assemblies, small industrial visual inspection cameras, miniature embedded monitoring modules for vending machines and cabinet monitoring cameras. Custom focal length, FOV and lens size services are available to satisfy personalized hardware matching demands from equipment manufacturers and module assemblers.

Designed for industrial machine vision and miniature CCTV security monitoring application.

Frequently Asked Questions

Q: Can this M12 lens work with 1/2.7-inch image sensors?

A: This lens is optimized for 1/4” sensors; using it on larger sensors will cause dark corners on the imaging edge and waste sensor pixels, so it is recommended to match the specified 1/4” format sensor.

Q: What is the working temperature range of this 4mm fixed focal lens?

A: The lens adopts all-glass lens group and stable plastic shell, supporting normal operation within -20℃ ~ 60℃ for most indoor security and industrial equipment working environments.

Q: Does the built-in IR cut filter support day-night switching function?

A: This lens integrates a fixed IR cut piece, suitable for daytime color monitoring scenes; if night infrared supplementary lighting imaging is needed, please select our model with removable IR filter.

Q: Is professional calibration needed after installing this lens to the camera module?

A: Standard M12 thread with unified TTL parameter; only simple focusing adjustment is required after locking the thread, no professional optical calibration is necessary for mass assembly.

Q: Why is the distortion value negative? What effect will it bring to actual imaging?

A: Negative distortion belongs to barrel distortion with the value controlled below -0.4%, the deviation is extremely tiny, basically invisible to human eyes and will not interfere with machine vision identification and surveillance video preview.

Q: Can I adjust the aperture value of this lens manually?

A: This product uses a fixed F2.8 fixed iris structure without adjustable aperture mechanical part, which can maintain stable light transmission and consistent imaging brightness for long-term continuous operation.
