C-Mount Lens – C3511014M12IR

C3511014M12IR is 35mm C-Mount CCTV lens, 12-Megapixels low-distortion, high-resolution wide-angle lens, F1.4 manual iris and focus, IR-corrected.

35mm 12MP 1.1″ C-Mount IR Corrected Machine Vision Lens

This 35mm C-Mount Lens is designed for 1.1″ sensors and supports up to 12MP resolution for demanding industrial imaging applications. With a fast F1.4 aperture, IR-corrected optical design, and 3m minimum object distance, it is well suited for high-resolution machine vision, factory automation, dimensional inspection, and applications requiring a longer working distance.

Product Core Highlights at a Glance

• 35mm fixed focal length provides a controlled field of view for longer-distance imaging.
• 12MP resolution supports detailed image capture with high-resolution 1.1″ industrial cameras.
• F1.4 maximum aperture provides high light-gathering capability for demanding inspection environments.
• IR-corrected optical design supports imaging systems using infrared illumination.
• 3m M.O.D. makes the lens particularly suitable for applications where the camera must remain several meters from the target.

C-Mount IR Corrected Lens Applications

High-Resolution Machine Vision Inspection

The 35mm focal length provides a relatively controlled field of view for inspecting targets from longer working distances. With a 24° horizontal FOV on a 1.1″ sensor and up to 12MP resolution, the lens can capture detailed information while maintaining a practical imaging area.

This configuration is suitable for inspection systems where the camera cannot be positioned close to the target, such as large production equipment, production lines, elevated inspection stations, and applications requiring physical clearance around the object.

Designed for high-resolution machine vision applications where working distance, image detail, and controlled field of view are important.

For help matching the lens with an appropriate camera sensor, refer to the Sensor Guide and Lens Selection Guide.

Long-Working-Distance Factory Automation

The 3m minimum object distance is an important characteristic for industrial installations where the camera needs to be positioned away from the inspection target.

As an FA Lens, it can be integrated into fixed-position automation equipment for:

• Large-part inspection
• Assembly verification
• Product surface inspection
• Dimensional inspection
• Position and alignment detection
• Production-line monitoring
• Automated quality control
• Robotic inspection stations

The fixed 35mm focal length also provides predictable optical behavior, which is useful when the camera position is established during machine design.

IR-Assisted Industrial Imaging

This IR Corrected Lens is designed for applications where infrared illumination forms part of the imaging system. IR correction helps the optical system maintain more consistent focusing behavior when the operating wavelength extends into the near-infrared range.

Potential applications include industrial inspection using IR lighting, machine vision systems with visible/IR illumination, and controlled imaging environments where wavelength-related focus variation needs to be considered.

Frequently Asked Questions

Q1: What sensor size is this 35mm C-Mount Lens designed for?
A: The lens is designed for 1.1″ sensors and has a maximum image format of Φ17.6mm.

Q2: What resolution does this industrial lens support?
A: The lens supports up to 12MP resolution, making it suitable for high-resolution machine vision and industrial inspection cameras.

Q3: What is the field of view of the 35mm lens?
A: With a 1.1″ sensor, the FOV is 29.5° diagonal, 24° horizontal, and 17.5° vertical.

Q4: Why is the 3m M.O.D. important?
A: A 3m minimum object distance makes the lens suitable for installations where the camera needs to remain relatively far from the target. This can be useful when equipment structure, safety clearance, or the physical size of the inspection area limits camera placement.

Q5: Is this lens IR corrected?
A: Yes. The optical design is IR corrected, making it suitable for machine vision systems that incorporate infrared illumination.

Q6: What is the maximum aperture?
A: The maximum aperture is F1.4. The manual iris allows the user to adjust the aperture according to illumination and depth-of-field requirements.

Q7: Is the 35mm lens a fixed focal lens?
A: Yes. The 35mm focal length is fixed. This makes it suitable for dedicated inspection stations where the camera and target positions are relatively stable.

Q8: How can I check whether the 35mm focal length provides enough coverage?
A: Field of view depends on the sensor format and working distance. You can use TOWIN’s FOV Calculator to estimate image coverage for your specific camera and installation distance.
