Low Distortion Lens – M91612302347

M91612302347 is 16mm Aspherical low distortion lens for machine vision, 1/2.3″ M9X0.5 mount lens(TTL 16.1mm), High-Resolution 5-Megapixel.

16mm M9 5MP Low Distortion Industrial Lens

This 16mm M9 industrial lens is a compact fixed focal lens designed for 1/2.3″ sensors and 5MP imaging applications. With distortion below 1%, a 23° horizontal field of view, and a 0.1m minimum object distance, it is well suited to compact machine vision systems requiring controlled geometry and close-range detailed imaging.

When selecting a fixed focal lens, sensor format, working distance and target coverage should be evaluated together. The Lens Selection Guide provides a useful reference for matching these parameters to an imaging system.

Product Core Highlights

• 16mm fixed focal length for controlled, narrow-angle imaging
• <1% distortion for stable geometric reproduction
• 5MP resolution for detailed image capture
• 0.1m M.O.D. for close-range inspection
• M9 × 0.5 mount for compact camera integration

16mm M9 Low Distortion Lens Applications

Core Application Scenes

This 16mm low distortion industrial lens is designed for compact imaging systems that need more concentrated scene coverage than a standard wide-angle lens. Its 23° horizontal and 17.5° vertical FOV allow the camera to focus on a defined target area while limiting unnecessary background information.

The combination of 16mm focal length, <1% distortion, and 0.1m M.O.D. makes the lens particularly useful for close-range inspection of components where image geometry needs to remain consistent. System builders can fit this lens into compact inspection cameras to examine connectors, electronic components, mechanical parts, printed features, labels, and other relatively small targets.

For embedded machine vision equipment, the M9 × 0.5 mount offers a smaller mechanical interface than conventional C-Mount or CS-Mount systems. This makes the lens suitable for camera modules installed inside compact inspection equipment, robotic end-effectors, automated instruments, and other space-constrained vision assemblies.

The F4.7 fixed aperture provides a consistent optical configuration for applications where the imaging conditions are relatively controlled. When the target distance and required image coverage are known, engineers can use the Focal Length Calculator to compare focal length requirements during system design.

Designed for close-range machine vision inspection, compact industrial cameras, and precision-oriented embedded imaging applications.

Compatible Device List

• Compact Machine Vision Cameras: Suitable for 1/2.3″ sensor camera modules requiring up to 5MP optical resolution and a relatively narrow field of view.
• Electronic Component Inspection Systems: The 16mm focal length and low distortion can help isolate small components and inspection regions from surrounding areas.
• Robotic Vision Modules: System integrators can fit the compact M9 interface inside small robotic or end‑of‑arm camera assemblies with constrained installation space.
• Embedded Inspection Cameras: Suitable for OEM camera modules used inside automated equipment, instruments, and compact vision devices.
• Industrial Recognition Systems: The controlled FOV can be useful for applications that need a defined target area for object recognition or feature detection.
• Close-Range Imaging Equipment: A 0.1m M.O.D. provides flexibility for applications where the camera must be positioned relatively close to the target.

For applications where dimensional accuracy and image geometry are important, engineers can also review the Distortion Guide when evaluating the effect of lens distortion on the final imaging result.
