ITS Lens – C701118M8

C701118M8 is a 70mm C-mount ITS CCTV lens.   It is long focal lenght for HD Megapixel 1″ sensors like AR1011HS, CMV4000.  It has a large aperture F1.8 manual iris for low light sensitive IP camera, security surveillance.

Product Overview

This 70mm C-Mount ITS CCTV lens is designed for high-resolution imaging systems that require narrow-angle viewing, extremely low distortion, and precise long-distance observation. With a 1″ image format, 8MP resolution, 10° horizontal field of view, and only 0.1% optical distortion, the lens provides a highly controlled image perspective for applications where accurate object positioning and image geometry are important. Its F1.8 aperture provides strong light transmission, while the manual iris, manual focus, and manual zoom configuration allows installers to fine-tune the optical system according to specific working conditions. The 15.45mm B.F.L. and 3m minimum object distance make the lens suitable for medium- to long-distance imaging rather than close-range inspection. Designed for precision long-range monitoring and industrial imaging applications, this C-Mount lens is well suited for machine vision, industrial inspection, traffic monitoring, perimeter surveillance, and high-resolution observation systems.

ITS CCTV Lens Advantages

0.1% Ultra-Low Distortion
The 0.1% distortion specification provides highly controlled image geometry, making this lens particularly suitable for applications where accurate object positioning, dimensional analysis, or reliable visual representation is important.

8MP High-Resolution Imaging
The 8MP optical configuration provides detailed image capture for industrial cameras, surveillance systems, and intelligent imaging applications requiring clear information from distant targets.

70mm Telephoto Focal Length
The 70mm focal length produces a narrow 10° horizontal field of view, concentrating the camera’s viewing area on distant or specific targets rather than providing broad-area coverage.

F1.8 Bright Aperture
The F1.8 aperture provides strong light-gathering capability, supporting high-quality imaging in demanding illumination conditions.

1″ Sensor Format
The 1″ image format supports larger industrial camera sensors and provides a suitable optical platform for high-resolution imaging applications.

Manual Optical Adjustment
Manual iris, focus, and zoom configurations provide system integrators with direct control over exposure, focusing, and optical positioning during camera installation and calibration.

C-Mount Interface
The C-Mount configuration is widely suited to industrial cameras, machine vision systems, professional surveillance cameras, and other imaging equipment requiring flexible optical integration.

ITS CCTV Lens Applications

Machine Vision & Industrial Inspection
The combination of 8MP resolution and only 0.1% distortion makes this lens suitable for machine vision applications where image geometry and object positioning need to remain highly controlled.

Long-Range Industrial Monitoring
The 70mm focal length and 10° horizontal FOV allow the ITS CCTV lens to focus on specific distant areas, making it useful for monitoring equipment, production processes, access points, and industrial facilities.

Traffic Monitoring
The narrow field of view can be advantageous for targeted traffic observation, vehicle monitoring, and intelligent transportation systems where the camera must concentrate on a defined area.

Perimeter Security
The telephoto configuration can help capture distant subjects at gates, fences, roads, industrial facilities, and restricted areas where a wider lens would include excessive surrounding information.

For security applications, see Smart Security Solutions.

High-Resolution Observation
The 8MP resolution, 70mm focal length, and 0.1% distortion make this ITS CCTV lens suitable for specialized observation systems requiring detailed imaging of relatively distant targets.

Lens Selection & Technical Considerations

70mm Focal Length and 10° FOV
The 70mm focal length provides a 10° horizontal field of view, creating a narrow viewing angle suitable for targeted observation and distant subjects. Unlike a wide-angle lens, this configuration prioritizes target concentration and detail over broad scene coverage.

When selecting the focal length, consider camera-to-target distance, target dimensions, sensor size, and required field of view. TOWIN’s FOV Calculator can help evaluate the relationship between these parameters.

Ultra-Low Distortion
With distortion of only 0.1%, this lens is particularly suitable for systems where maintaining accurate image geometry is important. Low distortion can reduce geometric deviations near the edges of the image and provide a more reliable visual representation.

1″ Sensor Compatibility
The lens is designed for a 1″ image format and supports 8MP resolution. The camera sensor should be matched with the lens image format to ensure proper image coverage and avoid vignetting.

F1.8 Aperture
The F1.8 aperture provides strong light transmission and can help maintain image brightness when lighting conditions are limited. For industrial and outdoor applications, actual image performance will also depend on sensor sensitivity, exposure settings, and available illumination.

Manual Iris, Focus and Zoom
The manual iris provides direct aperture adjustment, while manual focus allows precise focusing at the required working distance. The manual zoom configuration provides optical adjustment during system setup and integration.

3m Minimum Object Distance
The specified 3m M.O.D. indicates that this lens is intended for medium- and long-distance imaging. It is not optimized for very close-range inspection, so the target distance should be evaluated before selecting the lens.

Frequently Asked Questions

Q: What applications is this 70mm C-Mount lens suitable for?
A: This lens is suitable for machine vision, industrial inspection, long-range monitoring, traffic observation, perimeter security, and other high-resolution imaging applications requiring a narrow field of view and very low distortion.

Q: What is the field of view of this 70mm lens?
A: The lens provides a 10° horizontal field of view. This narrow viewing angle concentrates the camera’s coverage on a specific area or distant target.

Q: What sensor size does this lens support?
A: The lens is designed for a 1″ image format and supports 8MP resolution. The camera sensor should be matched to the lens image format during system design.

Q: Why is 0.1% distortion important?
A: Very low distortion helps preserve image geometry and reduces optical deformation across the image. This can be valuable for inspection, measurement-related imaging, object positioning, and other applications where image accuracy matters.

Q: Is the 70mm focal length suitable for long-distance imaging?
A: Yes. The 70mm focal length and 10° horizontal FOV provide a concentrated viewing angle suitable for distant subjects and targeted observation.

Q: What is the minimum object distance?
A: The specified M.O.D. is 3m, so the lens is primarily intended for medium- and long-distance imaging rather than close-range applications.

Q: Can TOWIN customize this C-Mount lens?
A: TOWIN supports OEM and ODM optical development for industrial, machine vision, traffic, and surveillance projects. Requirements such as focal length, FOV, distortion, sensor format, aperture, mechanical dimensions, and optical performance can be evaluated according to the application.
