PMS-LFGH-1216M 12mm 5MP 1″ C-Mount Machine Vision Lens

12mm 5MP Machine Vision Lens for 1″ Sensors

The POMEAS PMS-LFGH-1216M is a 12mm 5MP machine vision lens designed for C-mount industrial cameras with sensor formats up to 1 inch. Its Ø16 mm image circle supports large-format sensors while maintaining a compact structure for easier integration into machine vision equipment.

Featuring an adjustable F1.6–F22 iris, low optical distortion and separate locking screws for focus and aperture, this fixed focal length lens is suitable for stable industrial imaging, automated inspection, positioning and production-line vision applications.

Key Features

Supports Sensors up to 1 Inch

The lens provides an Ø16 mm image circle and supports 1-inch sensors measuring up to 12.8 × 9.6 mm. It can also be used with smaller sensor formats, including 2/3-inch industrial cameras.

12mm Focal Length for a Wider Field of View

The 12mm focal length provides a relatively wide viewing angle for machine vision systems. It is suitable for applications that need to capture a larger inspection area from a fixed camera position.

5MP Optical Resolution

Rated for 5-megapixel machine vision applications, the lens is designed to deliver clear industrial images when matched with a suitable camera sensor and working distance.

Low Optical Distortion

Optical distortion is specified at approximately -0.04% at an image height of 8.0 mm. Low distortion helps reduce geometric deformation in positioning, recognition and general inspection applications.

Adjustable F1.6–F22 Iris

The manual iris can be adjusted from F1.6 to F22, allowing the user to balance image brightness, depth of field and exposure according to the lighting conditions and inspection requirements.

Focus and Iris Locking Screws

Separate locking screws help secure the selected focus and aperture settings. This reduces accidental movement after installation and supports more stable operation in industrial equipment.

Standard C-Mount Interface

The standard C-mount connection allows the lens to be integrated with a wide range of compatible industrial cameras and machine vision systems.

Technical Specifications

Angular Field of View

The actual object-space field of view depends on the camera sensor dimensions, working distance and installation conditions.

Camera and Sensor Compatibility

The PMS-LFGH-1216M is designed for industrial cameras with a standard C-mount interface and a sensor format of 1 inch or smaller.

Compatible Sensor Formats

• 1-inch industrial camera sensors

• 2/3-inch industrial camera sensors

• Smaller C-mount camera sensors

When the same 12mm lens is used with a smaller sensor, the captured field of view becomes narrower. Sensor size should therefore be considered together with the required inspection area and working distance.

Before Selecting This Lens

Confirm the following information before placing an order:

• Camera model

• Camera mount type

• Sensor format

• Sensor resolution and pixel size

• Required field of view

• Available working distance

• Required inspection accuracy

• Lighting conditions

For cameras with a resolution higher than 5MP or with very small pixel sizes, optical performance should be confirmed through MTF data or an actual image test before final selection.

Typical Applications

Automated Visual Inspection

Suitable for capturing products, components and assemblies during automated inspection processes.

Object Recognition and Positioning

The low-distortion optical design can support general positioning, recognition and alignment applications.

Electronic Component Inspection

Suitable for imaging electronic components, connectors, assemblies and other industrial parts when the required field of view matches the 12mm focal length.

Production-Line Monitoring

The compact C-mount design can be integrated into automated production and monitoring equipment where stable focus and aperture settings are required.

General Industrial Imaging

Suitable for industrial cameras used in identification, appearance inspection, process observation and machine vision system integration.

How to Select the Correct Machine Vision Lens

A lens should not be selected by focal length alone. To confirm whether this 12mm machine vision lens is suitable, the following parameters should be evaluated together.

Sensor Size

The lens supports sensors up to 1 inch. A lens image circle must be large enough to cover the complete camera sensor without unwanted corner shading.

Field of View

A 12mm lens usually provides a wider field of view than a 16mm, 25mm or 35mm lens when used with the same camera and working distance.

Working Distance

The specified focusing range begins at approximately 1 metre. Applications requiring a significantly shorter working distance should be tested or matched with another lens model.

Camera Resolution

The lens is rated for 5MP applications. Using it on a higher-resolution camera does not automatically guarantee that the full camera resolution will be utilized.

Interface

The camera must use a C-mount interface or a suitable mechanical adapter. An adapter does not necessarily correct differences in flange distance, so mechanical and optical compatibility should both be confirmed.

Frequently Asked Questions

Can this 12mm machine vision lens cover a 1-inch sensor?

Yes. The PMS-LFGH-1216M provides an Ø16 mm image circle and is specified for sensors up to 1 inch, with maximum sensor dimensions of 12.8 × 9.6 mm.

Can the lens be used with a 2/3-inch industrial camera?

Yes. A 2/3-inch sensor is smaller than the maximum supported 1-inch format. The listed angular field of view on a 2/3-inch sensor is approximately 40.6° × 30.9°.

What field of view will this 12mm lens provide?

The actual field of view depends on the camera sensor size and working distance. Provide the camera model, sensor dimensions and installation distance for an application-specific field-of-view calculation.

Is this lens suitable for short-distance inspection?

The specified focusing range is approximately 1 metre to infinity. For applications below 1 metre, optical performance and focus capability should be tested before final selection.

Can I use this 5MP lens with a camera above 5MP?

The lens may be mechanically compatible with a higher-resolution C-mount camera, but it is rated for 5MP optical performance. Full resolution on a higher-megapixel or small-pixel camera should be confirmed through MTF data or an actual image test.
