CCL1212MPR

This 12mm M12 IR Corrected CCTV lens is designed for 1/2-inch sensors and supports up to 5-megapixel imaging, making it a practical optical solution for compact cameras requiring clear and stable image capture. With a fixed F1.8 aperture, the lens provides good light-gathering capability for imaging systems operating under varying lighting conditions. Its 39° diagonal, 30° horizontal, and 23° vertical field of view provide a balanced viewing range for applications that require more focused scene coverage than wide-angle lenses.

The IR Corrected CCTV lens features an M12x0.5 mount, 8.3mm back focal length, and a minimum object distance of 0.3m, allowing flexible integration into compact camera modules. The manual focus configuration enables precise optical adjustment during system integration. Its IR-corrected optical design helps maintain consistent imaging performance across visible and infrared wavelengths, making it suitable for cameras that require reliable day-and-night imaging. With a 6G optical construction, this 12mm M12 lens is well suited for CCTV, security cameras, smart traffic systems, machine vision, and other compact imaging applications.

Key Features

12mm Fixed Focal Length
The 12mm focal length provides a moderate field of view for applications requiring focused scene coverage without the strong perspective of an ultra-wide-angle lens.

5MP Resolution Support
Designed for 1/2-inch sensors and up to 5-megapixel imaging, providing clear image reproduction for security and industrial imaging systems.

F1.8 Fixed Aperture
The F1.8 aperture provides strong light-gathering capability, helping the camera maintain image quality in relatively low-light environments.

IR Corrected Optical Design
The IR-corrected design helps reduce focus shifts between visible and infrared wavelengths, supporting stable imaging for cameras equipped with IR illumination.

Compact M12x0.5 Mount
The standard M12x0.5 interface makes the lens suitable for compact camera modules and embedded imaging equipment.

0.3m Minimum Object Distance
A 0.3m M.O.D. provides practical close-range imaging capability for security, inspection, and other space-constrained applications.
