Low Distortion Lens – CCL1270610MPF

CCL1270610MPF is 1/2.7″ 6mm low distortion lens with IR cut Filter, 2-megapixel resolution, M16XP0.5 mount, F1.0 Large aperture CCTV lens.

6mm F1.0 M16 Low Distortion Lens

This 2MP 6mm M16 low distortion lens is designed for compact security and imaging systems requiring clear wide-angle coverage with distortion below 2.5%. With an F1.0 fixed aperture, 56° horizontal FOV, and integrated IR cut filter, it provides bright and stable imaging in space-constrained camera applications.

F1.0 M16 Low Distortion Lens Core Highlights

• Low Distortion Optical Design: Distortion below 2.5% helps preserve object shape and image geometry.
• F1.0 Large Aperture: Provides strong light-gathering capability for indoor and low-light imaging.
• 6mm Fixed Focal Length: Delivers a 56° horizontal field of view on a 1/2.7″ sensor.
• Compact M16 × P0.5 Mount: Suitable for camera modules and compact surveillance assemblies requiring a special mechanical interface.
• Integrated IR Cut Filter: Helps maintain more natural visible-light color reproduction during daytime operation.

F1.0 M16 Low Distortion Lens Applications

Core Application Scenes

This lens is designed for applications where wide-area coverage, low distortion, and high light transmission are required in a compact camera configuration.

Indoor Security Monitoring
The 6mm focal length provides a balanced field of view for offices, retail stores, entrances, corridors, and other indoor monitoring areas. The <2.5% distortion specification helps keep people and objects closer to their actual geometric proportions.

Low-Light CCTV Imaging
With an F1.0 aperture, the lens can collect more light than a typical smaller-aperture fixed lens. This makes it suitable for indoor scenes, building entrances, parking areas, and other environments where illumination can vary.

Compact Camera Modules
The M16 × P0.5 mount and 31.92mm TTL make this lens suitable for compact camera assemblies where mechanical dimensions and mounting compatibility are important.

Wide-Angle Observation
The 56° horizontal FOV provides broader scene coverage than a narrow-angle lens while retaining a low-distortion optical design. It can be used for general observation, access monitoring, equipment monitoring, and compact security cameras.

Designed for compact CCTV and security camera applications where low distortion, F1.0 brightness, and an integrated IR cut filter are required.

Frequently Asked Questions

Q1: What type of lens is this 6mm M16 lens?
A: It is a 6mm fixed focal lens with a low-distortion optical design, F1.0 fixed aperture, and M16 × P0.5 mount. It is suitable for compact CCTV and security imaging systems.

Q2: What is the field of view of the 6mm lens?
A: On a 1/2.7″ image sensor, the lens provides a 64° diagonal FOV, 56° horizontal FOV, and 31° vertical FOV.

Q3: Is this lens a fisheye lens?
A: No. Although it provides a relatively wide field of view, its distortion is below 2.5%. It is better classified as a low-distortion wide-angle fixed focal lens rather than a fisheye lens.

Q4: What is the advantage of the F1.0 aperture?
A: The F1.0 aperture provides high light transmission, which can help maintain brighter images when the available scene illumination is limited.

Q5: What does the IR cut filter do?
A: The integrated IR cut filter blocks infrared wavelengths during visible-light operation, helping the camera produce more natural color reproduction.

Q6: What sensor size is this lens designed for?
A: The specified image format is 1/2.7″. For reliable image quality and full field-of-view performance, the lens should be matched with a compatible sensor size.

Q7: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, allowing the lens to focus on objects from approximately 0.2 meters under the specified optical configuration.

Q8: Can TOWIN provide a similar lens with a different focal length or mount?
A: Yes. TOWIN develops fixed focal, low-distortion, CCTV, and special-mount optical solutions. Customers can contact TOWIN to discuss focal length, sensor format, mount, aperture, distortion, and mechanical requirements.
