Low Distortion Lens – C252314A2IR

C252314A2IR is C-Mount 25mm low distortion lens, 2-Megapixels resolution, DC Auto iris, F1.4-C large aperture Suitable for low-light environments.

25mm C-Mount Low Distortion Lens

This 25mm C-Mount fixed focal lens is designed for 2/3″ and 1/2″ camera sensors, delivering controlled fields of view with distortion below -1%. Its F1.4–C aperture, DC auto iris, manual focus, and 0.5m minimum object distance make it a flexible industrial lens for factory automation, machine vision, and professional surveillance systems.

For help matching the lens with a camera sensor, the Sensor Guide explains important sensor and image-format considerations. You can also use the Lens Selection Guide when selecting focal length and lens characteristics for a specific imaging system.

Product Core Highlights

• 25mm fixed focal length for stable, repeatable imaging.
• 2/3″ and 1/2″ FOV specifications for flexible camera integration.
• 2MP resolution for standard industrial and surveillance imaging.
• F1.4–C aperture range with DC auto iris control.
• Less than 1% distortion for controlled image geometry.

As part of the C-Mount Lenses range, this lens provides a practical optical configuration for systems that need a standard C-Mount interface, automatic iris control, and consistent framing from a fixed 25mm focal length.

C-Mount Low Distortion Lens Applications

Core Application Scenes

This 25mm C-Mount industrial lens is well suited to fixed-position imaging systems where the camera needs to maintain a consistent view of a defined inspection or monitoring area. Its 25mm focal length provides a moderately narrow field of view, making it appropriate for observing individual work areas, equipment sections, production components, or controlled access points.

In factory automation, the lens can be integrated into inspection stations where a camera is permanently mounted above or beside a production line. The fixed focal length helps maintain consistent image composition between inspection cycles, while the manual focus allows the installer to optimize sharpness during initial system setup.

The lens supports FOV specifications for both 2/3″ and 1/2″ sensors, giving system integrators more flexibility when selecting compatible industrial cameras. This is particularly useful when an existing camera platform needs to be replaced or upgraded without completely redesigning the optical configuration.

Its DC auto iris provides automatic aperture adjustment as illumination changes. This makes the lens practical for industrial environments where lighting may vary because of production-area illumination, equipment movement, or changes between different operating conditions.

With distortion below -1%, the lens can also be considered for applications where image geometry should remain relatively controlled, such as component positioning, visual verification, edge inspection, and equipment monitoring.

For projects where the required viewing area needs to be determined from sensor size and working distance, the FOV Calculator can help estimate the field of view before selecting the final optical configuration.

Designed for fixed-position factory automation, equipment inspection, and controlled industrial surveillance applications.
