CCTV Lens – C1212011818M3

C1212011818M3 is 12-120mm manual iris CCTV lens, 1/1.8″ C mount lens, low-distortion (<0.1%), with 3-Megapixels resolution, F1.8-16 aperture.

1/1.8″ 12-120mm C-Mount Low Distortion CCTV Lens

This 1/1.8-inch 12-120mm C-Mount CCTV lens provides a 40° to 2.9° horizontal field of view with less than 0.1% distortion. Its F1.8–16 aperture, manual iris, focus, and zoom controls make it suitable for industrial monitoring, security imaging, and applications requiring flexible focal-length adjustment.

C-Mount Low Distortion CCTV Lens Core Highlights

• 12–120mm 10× zoom range for flexible wide-to-telephoto framing
• <0.1% distortion helps maintain accurate image geometry
• F1.8–16 aperture range supports different lighting conditions
• C-Mount interface for compatibility with industrial and security cameras
• Manual zoom, focus, and iris provide precise optical adjustment

C-Mount Low Distortion CCTV Lens Applications

Core Application Scenes

This C-Mount zoom lens is designed for applications where the camera needs to switch between a relatively broad scene and a narrow field of view without changing the lens. The 12–120mm focal-length range provides a 10× optical zoom, while the 40° to 2.9° horizontal FOV allows operators to move from scene-level observation to detailed views of distant objects.

With distortion below 0.1%, the lens is particularly suitable for imaging tasks where straight-line geometry and positional consistency are important. The F1.8–16 aperture range also allows the optical system to be adjusted for different illumination conditions.

Designed for industrial monitoring and long-range security observation applications where flexible zoom control and very low optical distortion are required.

Compatible Device List

• Industrial monitoring cameras
• C-Mount security cameras
• Fixed-position surveillance cameras
• Industrial inspection camera systems
• Remote observation camera systems
• Long-range monitoring equipment
• Machine monitoring cameras requiring manual optical adjustment

Recommended Application Categories

For TOWIN’s product structure, this lens is best positioned under C-Mount Lenses, Industrial Lens, CCTV Lens, Zoom Lens, and Low Distortion Lens. Its 12–120mm range and manual operation make it particularly relevant to applications requiring variable viewing distance rather than fixed-focal machine vision inspection.

Frequently Asked Questions

Q: What type of camera is this 12-120mm lens designed for?
A: It is designed for cameras using a 1/1.8″ image format and a C-Mount interface. It can be used with compatible industrial and security camera systems.

Q: What is the horizontal field of view of this zoom lens?
A: The horizontal FOV ranges from approximately 40° at the 12mm focal length to 2.9° at 120mm.

Q: How much distortion does this lens have?
A: The specified optical distortion is less than 0.1%, making it suitable for applications where maintaining image geometry is important.

Q: Does the lens have a motorized zoom?
A: No. The supplied specification identifies the zoom as manual, allowing the operator or installer to adjust the focal length manually.

Q: What is the aperture range?
A: The lens has a manual F1.8–16 aperture range, allowing the amount of light entering the optical system to be adjusted according to the imaging environment.

Q: What is the minimum object distance?
A: The specified M.O.D. is 1.2m, so the lens is intended for applications where the target is positioned at least approximately 1.2m from the optical system.

Q: What does the 12–120mm focal-length range provide?
A: It provides a 10× zoom range, allowing the same camera to cover relatively wide scenes at 12mm and narrow, distant targets at 120mm.
