CCL122520MP

Description

This premium 25mm M12 lens features a large 1/2″ image format and 2MP resolution, delivering sharp, high-contrast imaging from the center to the periphery. Engineered with an optical distortion of less than 1.5% and built-in IR correction, this fixed focal lens eliminates focus shift between day and night environments. It is the ideal high-reliability optical component for high-precision machine vision, industrial inspection, and long-range CCTV surveillance.

Key Product Highlights

• Large 1/2″ Format & 25mm Focal Length: Offers a narrow, long-range field of view (19° D / 15° H / 11° V) to capture distant details with high pixel density.
• Ultra-Low Optical Distortion (<1.5%): Minimizes image warping to guarantee high accuracy in dimensional measurement and automated inspection.
• Day & Night IR-Corrected Optic: Eliminates focus drift under infrared illumination, delivering crisp 2MP images 24/7 without manual refocusing.
• 0.2m Minimum Object Distance (M.O.D.): Supports short-range, close-up macro imaging, perfect for compact industrial workstations and automated testing lines.

Technical Specifications

This product is certified by RoHS and ISO9001 quality management system, supports third-party testing, and complies with EU and domestic security equipment access standards, ensuring reliable quality and full compliance.

Applications & Compatible Devices

Core Application Scenarios

This 25mm industrial lens is designed for precision-driven automated production lines and specialized surveillance. It excels in automated optical inspection (AOI) for PCBs, high-accuracy component positioning, and barcode reading where low distortion is mandatory. Its narrow field of view and 2MP resolution make it perfect for license plate recognition (LPR/ANPR) systems, gate access control, and perimeter security tracking under challenging outdoor lighting conditions. The 0.2m M.O.D. allows seamless deployment in tight medical diagnostics setups and scientific laboratory imaging.

Compatible Device List

• Sensors & Formats: Fully compatible with large 1/2″ CMOS/CCD sensors and backward compatible with 1/2.7″, 1/2.8″, and 1/3″ sensors (e.g., Sony IMX series).
• Industrial Cameras: Perfect fit for M12 board-level cameras, industrial smart cameras, and FA vision modules from brands like Basler, Hikrobot, and Dahua.
• Surveillance Hardware: Integrates smoothly into IP bullet cameras, traffic monitoring enclosures, and long-range CCTV systems without mechanical modifications.
• Customization: Supports tailored adjustments for specific optical filters (e.g., 850nm/940nm narrow bandpass) and mounting mechanics based on OEM requirements.

Frequently Asked Questions

Q1: What are the main benefits of a 1/2″ image format on an M12 lens?

A 1/2″ format is significantly larger than standard 1/3″ or 1/4″ mini lenses. It allows more light throughput, provides a wider dynamic range, reduces digital noise, and ensures compatibility with high-performance, large-format industrial image sensors.

Q2: What does “IR Corrected” mean for this 25mm lens?

Light of different wavelengths (visible light during the day and infrared light at night) refracts at different angles. This IR-corrected lens utilizes special extra-low dispersion glass to ensure both visible and IR light focus on the exact same focal plane, preventing nighttime image blur.

Q3: Can I use this M12 lens with a C-mount or CS-mount camera?

Yes, you can use this lens with C/CS-mount cameras by utilizing a standard M12-to-C/CS mount mechanical adapter. However, ensure that the camera’s sensor size does not exceed 1/2″ to avoid vignetting (dark corners).

Q4: Why is the <1.5% low distortion feature important for machine vision?

In automated inspection, sorting, and gauging, optical distortion causes straight lines to appear curved, which leads to measurement errors. A low distortion rate of <1.5% ensures geometric fidelity, allowing software algorithms to calculate dimensions accurately.

Q5: Is the focus adjustable on this fixed focal lens?

Yes, while the focal length is fixed at 25mm, the focus is manual. You can adjust the image sharpness for different working distances by screwing the lens further into or out of the M12 mount threads, then securing it with a locking ring.

Q6: Does this industrial lens support auto-iris functionality?

No, this lens features a fixed F2.0 aperture and a fixed iris. It is optimized for environments with controlled lighting (like factory floors with LED strobes) or cameras with electronic auto-shutter capabilities.
