Low Distortion Lens – C2501014A8

C2501014A8 is C-Mount 25mm 8-Megapixel low distortion lens, with manual focus and DC auto iris, compatible with both 1″ and 2/3″ sensors.

25mm C-Mount Low Distortion Lens

This 25mm C-Mount machine vision Low Distortion lens is designed for 1″ and 2/3″ image sensors, supporting up to 8MP resolution with a maximum image format of Φ16.8. Its F1.4–16 aperture, DC auto iris, manual focus, and 0.5m minimum object distance make it a versatile industrial lens for factory automation, machine inspection, and precision imaging systems.

For engineers selecting a lens for a larger-format industrial camera, the Sensor Guide provides useful information about image sensor formats and optical matching. The Lens Selection Guide can also help determine focal length and field-of-view requirements.

Product Core Highlights

• 1″ sensor coverage with a maximum image format of Φ16.8.
• 8MP resolution for detailed industrial inspection.
• 25mm fixed focal length for stable, repeatable imaging.
• F1.4–16 aperture range with DC auto iris control.
• Dual-format FOV specifications for 1″ and 2/3″ sensors.

As part of the C-Mount Lenses range, this lens is designed for industrial vision systems that require a larger sensor image circle and high-resolution optical performance. Its 1″ compatibility gives system integrators greater flexibility when selecting cameras for demanding inspection applications.

C-Mount Low Distortion Lens Applications

Core Application Scenes

This 25mm 8MP industrial lens is particularly suited to machine vision systems using larger-format sensors where a standard 25mm focal length needs to cover a relatively broad inspection area. The 1″ FOV of 35° diagonal, 28° horizontal, and 21° vertical provides useful coverage for inspecting components, assemblies, and defined sections of automated production equipment.

For factory automation and FA applications, the 8MP resolution allows the imaging system to capture more detailed information from manufactured parts, printed markings, component surfaces, and assembly features. The larger image format also makes the lens suitable for industrial cameras where sensor size exceeds the typical 2/3″ machine vision format.

The F1.4 maximum aperture provides strong light-gathering capability for inspection systems using short exposure times or controlled production-line illumination. The aperture can be adjusted through the F1.4–16 range according to the available light and required depth of field, while the DC auto iris provides automatic exposure adjustment when illumination conditions change.

The 0.5m M.O.D. makes the lens suitable for medium-distance inspection setups where the camera is positioned at a controlled distance from the workpiece. Manual focus allows the integrator to establish precise focus during installation, while the fixed 25mm focal length maintains consistent image composition during production.

For systems where field coverage needs to be evaluated before installation, the FOV Calculator can be used to estimate the relationship between sensor size, focal length, working distance, and field of view.

Designed for high-resolution factory automation, component inspection, and large-format machine vision imaging.
