Wide Angle Lens – CCL132036MPF

CCL132036MPF is 3.6mm F2.0 Wide angle 1/3.2″ CCTV lens IR cut filter, S-Mount Lenses with Low F-number (Fast Lenses), security surveillance lens.

3.6mm M12 3MP Wide Angle Lens with High Optical Resolution

This 3.6mm M12 wide angle lens is designed for 1/3.2″ camera systems requiring broad scene coverage together with defined optical resolution performance. With a 96° diagonal FOV, 76° horizontal FOV, 55° vertical FOV, 3MP resolution, and F2.0 aperture, it provides a balanced optical solution for compact industrial imaging, embedded vision, monitoring, and machine vision applications.

Featuring an MTF specification of 0.5 at 180 lp/mm, a 6G optical construction, and a 7.25mm BFL, the lens is designed for applications where optical detail and compact mechanical integration both matter. The M12×0.5 mount, fixed iris, and manual focus configuration further simplify integration into compact camera systems.

M12 Wide Angle Lens Core Highlights

• 96° Wide-Angle Field of View: The 3.6mm focal length delivers 96° diagonal and 76° horizontal FOV for broad scene coverage in compact camera systems.
• Defined MTF Performance: An MTF specification of 0.5 at 180 lp/mm provides a measurable optical performance reference for system designers evaluating image detail.
• 3MP Optical Performance: Designed for 1/3.2″ imaging systems requiring practical megapixel-level resolution with a compact optical assembly.
• F2.0 Aperture: The F2.0 aperture provides a relatively wide optical opening for general indoor and embedded imaging environments.
• 6G Optical Construction: The 6G structure supports a compact optical design while maintaining the performance requirements of wide-angle imaging applications.

M12 Wide Angle Lens Applications

Core Application Scenes

This 3.6mm lens is designed for imaging systems that need wide-area coverage while maintaining a defined level of optical resolution. Its 76° horizontal FOV allows a camera to capture a relatively broad scene from a compact installation position.

The MTF specification of 0.5 at 180 lp/mm makes this model particularly useful when lens designers need a measurable reference for optical detail performance rather than evaluating the lens only by its field of view. Combined with 3MP resolution and an F2.0 aperture, it can support a range of compact imaging applications.

The 0.3m minimum object distance also makes the lens suitable for relatively close-range scene monitoring, equipment observation, and embedded vision applications.

Designed for compact wide-angle industrial imaging applications, this lens can be considered when FOV, optical resolution, and mechanical size need to be balanced.

For more demanding inspection systems, TOWIN’s Machine Vision solutions provide additional optical configurations for different sensor formats, resolutions, and working distances.

Frequently Asked Questions

Q: What sensor format is this 3.6mm M12 lens designed for?
A: This model is designed for a 1/3.2″ image format and provides a 96° diagonal, 76° horizontal, and 55° vertical field of view.

Q: What does the MTF specification of 0.5 at 180 lp/mm mean?
A: It provides a measurable reference for the lens’s ability to maintain contrast at a spatial frequency of 180 line pairs per millimeter, helping system designers evaluate optical detail performance.

Q: Is this lens suitable for wide-angle imaging?
A: Yes. With a 96° diagonal and 76° horizontal FOV, the 3.6mm focal length provides broad scene coverage for compact imaging systems.

Q: Is this a low distortion lens?
A: No. The specified distortion is -29%, so this model should be positioned as a wide-angle lens rather than a dedicated low distortion lens.

Q: Does the IR cut configuration make this an IR corrected lens?
A: No. “IR Cut” indicates an infrared-cut filter configuration. It does not confirm IR-corrected optical performance across visible and near-infrared wavelengths.

Q: What is the minimum object distance of this lens?
A: The specified minimum object distance is 0.3m, allowing the lens to capture relatively close objects in equipment monitoring and embedded imaging applications.

Q: What type of mount does this lens use?
A: The lens uses an M12×0.5 mount, a common interface for compact camera modules, embedded vision systems, and small industrial imaging devices.

Q: Can this lens be used for machine vision?
A: Yes. It can be considered for machine vision applications that prioritize broad scene coverage, compact integration, and measurable optical performance. Applications requiring very low distortion may require a different lens design.
