CCTV Lens – CCL1306MMP

CCL1306MMP CCTV lens 1/3″6mm low light F1.2 IR corrected CS-mount lens manual Iris day night surveillance

6mm CS-Mount IR Corrected CCTV Lens

This 6mm CS-mount CCTV lens is designed for 1/3″ image sensors and provides a 45° horizontal field of view for stable, medium-angle surveillance imaging. With a fixed focal length, manual iris, manual focus, and IR correction, it is well suited for security cameras and professional monitoring systems that require consistent image performance across visible and near-infrared imaging conditions.

CS-Mount CCTV Lens Core Highlights

• 6mm Fixed Focal Length – Delivers a stable 45° horizontal field of view.
• F1.2 Wide Aperture – Provides strong light-gathering capability for demanding monitoring environments.
• IR Corrected Optical Design – Helps maintain focus consistency when imaging with near-infrared illumination.
• CS-Mount Compatibility – Designed for CS-mount CCTV and professional security camera platforms.
• Manual Optical Control – Manual iris and focus allow installers to fine-tune imaging for specific scenes.

CS-Mount CCTV Lens Applications

Core Application Scenes

This 6mm CS-mount IR corrected lens is optimized for surveillance scenes where a controlled field of view is more important than ultra-wide coverage. Its 45° horizontal FOV provides a practical balance between scene coverage and subject detail, making it suitable for monitoring entrances, corridors, indoor work areas, restricted zones, and fixed observation points.

The F1.2 aperture is particularly valuable in security environments with limited or changing illumination. Combined with the IR-corrected design, the lens can support camera systems that switch between visible-light imaging and infrared-assisted monitoring, helping maintain consistent optical focus when illumination conditions change.

For professional security installations, the CS interface makes this lens a practical option for interchangeable CCTV camera systems where installers need manual control over focus and aperture during commissioning. The 0.2m minimum object distance also allows the lens to be used for relatively close-range monitoring rather than being limited to distant surveillance scenes.

Compatible Device List

• CS-Mount CCTV Cameras: Suitable for fixed security camera platforms using a standard CS-mount interface.
• Indoor Surveillance Cameras: Well suited to entrance monitoring, corridors, access areas, retail interiors, and controlled indoor spaces where a 45° horizontal FOV provides focused coverage.
• IR-Illuminated Security Systems: The IR-corrected optical design makes it suitable for cameras using near-infrared illumination for low-light or nighttime observation.
• Industrial Monitoring Cameras: Can be integrated into fixed industrial monitoring systems where manual optical adjustment and consistent framing are required.
• Embedded Security Camera Modules: The fixed focal design provides predictable imaging geometry for camera assemblies with a defined installation distance.

For broader CCTV product options, this lens can be evaluated alongside TOWIN’s CS Mount Lenses, while the Fixed Focal Megapixel Lens category provides additional fixed-focus options for security imaging systems.

When selecting the correct focal length for a camera installation, engineers can use the FOV Calculator to estimate the relationship between sensor size, focal length, working distance, and field of view. For general optical selection considerations, the Lens Selection Guide provides additional guidance on matching lens characteristics to imaging requirements.

Designed for fixed-position CCTV surveillance, IR-assisted security monitoring, and industrial observation applications.

Frequently Asked Questions

Q: What type of camera is this 6mm CS-mount lens designed for?

A: This lens is primarily designed for CS-mount CCTV and security camera systems using 1/3″ image sensors. It can also be considered for fixed industrial monitoring cameras with compatible CS interfaces.

Q: What field of view does the 6mm lens provide?

A: The lens provides a 45° horizontal field of view on the specified 1/3″ image format, making it suitable for focused surveillance rather than ultra-wide scene coverage.

Q: Is this a fixed focal length lens?

A: Yes. The focal length is fixed at 6mm, providing predictable framing and a consistent field of view without optical zoom adjustment.

Q: Why is IR correction important for CCTV applications?

A: IR correction helps reduce focus shifts between visible light and near-infrared wavelengths. This is particularly useful for surveillance cameras that use IR illumination for nighttime or low-light monitoring.

Q: Does this lens have a manual iris?

A: Yes. The lens uses a manual iris, allowing installers to adjust the aperture according to the available light level and required depth of field during camera setup.

Q: What is the minimum object distance of this lens?

A: The specified minimum object distance reaches 0.2 m. This lets the lens handle relatively close‑range monitoring applications alongside standard surveillance scenes.

Q: How can I select the right focal length for my camera system?

A: Focal length should be selected according to the sensor format, required field of view, working distance, and target size. TOWIN’s Lens Selection Guide and FOV Calculator can help engineers evaluate these factors before choosing a lens.
