C-Mount Lens – C2001014M8

Le C2001014M8 est un objectif à monture C de 20 mm et 8 mégapixels, avec iris et mise au point manuels, un objectif haute résolution à faible distorsion, adapté aux conditions de faible luminosité grâce à son ouverture F1.4.

20mm 8MP C-Mount Industrial Machine Vision Lens

This 20mm C-Mount Lens is designed for 8MP industrial cameras using 1″ or 2/3″ sensors. With an F1.4 aperture, 0.5m minimum object distance, and manual iris and focus, it provides a flexible fixed focal length solution for machine vision, factory automation, component inspection, and automated quality control systems.

Product Core Highlights at a Glance

• 20mm fixed focal length for balanced coverage in industrial imaging setups.
• 8MP resolution supports detailed inspection with high-resolution industrial cameras.
• 1″ and 2/3″ sensor compatibility provides flexibility when configuring different camera platforms.
• F1.4 maximum aperture provides strong light-gathering capability for industrial imaging.
• 0.5m M.O.D. supports inspection applications where the camera must operate relatively close to the target.

C-Mount Machine Vision Lens Applications

Machine Vision Inspection

The 20mm focal length provides a practical field of view for inspecting components at short to medium working distances. On a 1″ sensor, the lens provides a 35.5° horizontal FOV, while the 2/3″ configuration provides a 25° horizontal FOV.

This makes the lens suitable for applications where the inspection area needs to be clearly captured without using an extremely wide-angle optical design. The 8MP resolution also provides sufficient image detail for automated detection, classification, and dimensional inspection tasks.

Designed for machine vision inspection applications requiring a fixed focal length and high-resolution imaging.

For selecting the appropriate camera and sensor combination, the Sensor Guide can help system integrators evaluate sensor size and image coverage.

Factory Automation & FA Equipment

As an FA Lens, this model is suitable for fixed-position cameras installed on production equipment. Its manual iris and focus allow the optical configuration to be adjusted during machine setup and commissioning.

Typical applications include:

• Component presence and absence inspection
• Part orientation verification
• Assembly inspection
• Surface defect detection
• Dimensional checking
• Packaging inspection
• Conveyor-based quality control
• Automated positioning and alignment

Dual Sensor-Format Flexibility

One practical advantage of this Industrial Lens is its compatibility with both 1″ and 2/3″ sensor formats. The resulting field of view changes according to the sensor size, allowing the same 20mm focal length platform to be considered for different camera configurations.

For a 1″ sensor, the lens offers a wider coverage of 44.5° diagonal and 35.5° horizontal. With a 2/3″ sensor, the coverage becomes 31° diagonal and 25° horizontal, producing a tighter imaging area.

This makes it useful for OEM machine builders and vision integrators working with different industrial camera specifications.

Q4: What is the FOV on a 2/3″ sensor?
A: On a 2/3″ sensor, the FOV is 31° diagonal, 25° horizontal, and 18.5° vertical.

Q5: Is this lens suitable for 8MP machine vision cameras?
A: Yes. The lens is specified for 8MP resolution and can be used with compatible 1″ or 2/3″ C-Mount industrial cameras.

Q6: What is the maximum aperture of the lens?
A: The maximum aperture is F1.4. The manual iris allows the aperture to be adjusted according to the lighting conditions and required depth of field.

Q7: What is the minimum object distance?
A: The M.O.D. is 0.5m. The actual installation distance should be selected according to the target dimensions, required FOV, and camera configuration.

Q8: How do I determine whether 20mm is the correct focal length for my application?
A: Focal length should be selected based on sensor size, working distance, and required field of view. TOWIN’s FOV Calculator can help estimate the required optical configuration before selecting a lens.
