Low Distortion Lens – S35012001028F

S35012001028F-Low distortion fixed-focus manual M12-mount 1/2″ 2MP security lens with 35mm focal length, 13° diagonal FOV, F2.8 aperture, and IR filter support.

35mm M12 Low Distortion Lens

This 35mm 2MP M12 low distortion lens is designed for precise, narrow-field imaging where controlled perspective and low geometric distortion are important. With less than 0.8% distortion, a 13° diagonal FOV, and an M12x0.5 mount, it is well suited to compact inspection cameras, industrial monitoring systems, and machine vision applications requiring stable image geometry.

The 35mm fixed focal design provides a relatively narrow viewing angle for capturing distant or localized targets without the excessive perspective distortion associated with wide-angle optics.

• 35mm Fixed Focal Length: Provides a narrow 13° diagonal FOV for focused target imaging.
• 1/2″ Sensor Support: Designed to cover compact 1/2″ imaging sensors.
• M12x0.5 Mount: Enables integration into compact camera and embedded vision platforms.
• Manual Focus & Fixed Iris: Allows straightforward optical adjustment during camera integration.

M12 Low Distortion Lens Applications

Core Application Scenes

This 35mm M12 low distortion lens is particularly suitable for imaging tasks where the camera needs to isolate a relatively distant or localized target rather than capture a large scene. Its 13° diagonal field of view helps concentrate the image on a specific area, while the <0.8% distortion specification helps preserve the relative shape and position of objects across the image.

For compact industrial inspection systems, the lens can be used where a narrow viewing angle and controlled geometric distortion are more important than broad scene coverage. It can support visual inspection of components, product features, labels, and localized production areas when the camera must be positioned away from the target.

The lens can also be considered for machine vision monitoring and recognition systems that use compact camera modules with a 1/2″ sensor. Its fixed 35mm focal length provides consistent framing once the camera position has been established, making it practical for dedicated inspection stations with a fixed working configuration. For broader machine vision applications, see TOWIN’s Machine Vision solutions.

For industrial monitoring and localized surveillance, the narrow FOV can help concentrate imaging on entrances, equipment zones, production details, or other specific areas without requiring a large-angle lens. The M12 interface also makes the lens suitable for compact camera housings where installation space is limited.

The <0.8% distortion specification makes this lens especially relevant when maintaining image geometry is important. Engineers can use TOWIN’s Distortion Guide when evaluating whether the distortion characteristics are appropriate for their imaging requirements.
