1 Inch 5MP 16mm C-Mount Machine Vision Lens | POMEAS

Product Description

1 Inch 5MP 16mm C-Mount Machine Vision Lens

The POMEAS PMS-LFGH-1616(A) is a 5MP, 16mm C-mount machine vision lens developed for industrial cameras with sensors up to 1 inch. It combines a fixed 16mm focal length, an adjustable F1.6–F22 iris and a compact C-mount housing for integration into machine vision and factory automation systems.

The lens supports a maximum sensor area of 12.8 × 9.6mm and can also be used with smaller formats such as 2/3-inch sensors. Separate focus and iris locking screws help prevent accidental setting changes after installation, providing more consistent imaging during continuous machine operation.

With a specified focusing range from 1m to infinity, this 1 inch C-mount lens is particularly suitable for medium- and long-distance industrial imaging tasks rather than close-range macro inspection.

Key Features

Supports Sensors up to 1 Inch

The lens provides an image format suitable for industrial cameras with sensor dimensions up to 12.8 × 9.6mm. Using a lens designed for the required sensor size helps reduce the risk of image-circle limitations or corner shading.

5MP Optical Resolution

The PMS-LFGH-1616(A) is rated for cameras with resolutions up to 5 megapixels. It can be used in general-purpose industrial imaging systems that require clear feature recognition, positioning and inspection.

16mm Fixed Focal Length

The fixed 16mm focal length provides a practical balance between field of view and image detail. It is suitable for systems where a shorter focal length produces too wide a view and a longer focal length limits the inspection area.

Adjustable F1.6–F22 Iris

The wide iris adjustment range allows system integrators to balance image brightness, exposure time and depth of field according to the available illumination and inspection speed.

A wider aperture helps collect more light, while a smaller aperture can increase depth of field when the inspected object has height variation.

Focus and Iris Locking Screws

Independent locking screws are provided for both focus and iris adjustment. After the required image and exposure settings are confirmed, the screws can be tightened to help maintain the selected configuration.

Standard C-Mount Interface

The standard C-mount design simplifies integration with compatible industrial cameras. Before purchasing, confirm that the camera uses a C-mount interface rather than a CS-mount or another lens connection.

Technical Specifications

Angular Field of View

Actual object field of view depends on the camera sensor dimensions, working distance and installation configuration.

Camera and System Compatibility

Sensor Size

This 16mm C-mount machine vision lens supports sensors up to 1 inch. It may also be paired with smaller sensors, including 2/3-inch formats, provided that the required field of view is confirmed.

A smaller sensor uses a reduced portion of the image circle and therefore produces a narrower field of view with the same lens and working distance.

Camera Resolution

The lens is specified for cameras up to 5MP. Camera resolution alone does not determine final measurement accuracy. Pixel size, sensor dimensions, working distance, field of view, lighting, mechanical stability and image-processing calibration must also be considered.

For dimensional measurement or micron-level inspection, confirm the required object-side resolution rather than selecting the lens only by megapixel rating.

Working and Focusing Distance

The specified focusing range starts at 1 metre and extends to infinity. This makes the lens more appropriate for medium- or long-distance imaging applications.

For inspection systems requiring a working distance shorter than 1 metre, select a lens specifically designed for shorter focusing distances or confirm a customized optical solution.

Distortion Considerations

The specified distortion is -3.73% at y = 8.0mm. For presence detection, recognition and general inspection, this may be managed through system setup and image processing.

For dimensional measurement, gauging or applications requiring accurate edge-to-edge geometry, distortion calibration should be included in the vision software. A telecentric or lower-distortion lens may be more suitable when measurement error must be minimized.

Aperture Selection

Use a wider aperture when the system requires shorter exposure times or when illumination is limited. Use a smaller aperture when additional depth of field is needed.

Avoid closing the iris more than necessary, because excessive stopping down may reduce image detail due to diffraction.

Typical Applications

The PMS-LFGH-1616(A) industrial camera lens can be integrated into applications such as:

• Automated product appearance inspection
• Presence and absence detection
• Component positioning and alignment
• Electronic manufacturing inspection
• Assembly verification
• Label and character recognition
• Factory automation camera systems
• General machine vision image acquisition

Application suitability depends on the camera sensor, required field of view, working distance, object size, inspection accuracy and illumination conditions.

Why Choose the PMS-LFGH-1616(A)?

The PMS-LFGH-1616(A) combines a large 1-inch sensor format, 5MP optical rating and 16mm focal length in a compact C-mount configuration.

Its focus and iris locking mechanisms make it easier to preserve optical settings after the system has been adjusted. The F1.6–F22 iris range also provides flexibility when balancing exposure, illumination and depth of field.

For system integrators selecting a 5MP machine vision lens, the model provides clearly defined optical and mechanical specifications for camera compatibility evaluation.

Frequently Asked Questions

Is the PMS-LFGH-1616(A) compatible with a 1-inch camera?

Yes. The lens supports a maximum sensor size of 1 inch, corresponding to sensor dimensions up to 12.8 × 9.6mm.

Camera mount type must also be checked. The camera should have a compatible C-mount interface.

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

Yes. A 2/3-inch sensor is smaller than the maximum supported image format. The lens can therefore be used with a compatible 2/3-inch C-mount camera.

The resulting field of view will be narrower than it is on a 1-inch sensor.

Is this a zoom lens?

No. The PMS-LFGH-1616(A) is a fixed focal length lens with a 16mm focal length.

The field of view is adjusted primarily by changing the working distance, camera sensor size or lens focal length.

Is it suitable for close-range inspection?

The specified focusing range is 1m to infinity, so the lens is not designed primarily for short working distance or macro inspection.

For close-range inspection, select a lens with a shorter minimum object distance or provide the required field of view and working distance for optical evaluation.

How should I select a matching industrial camera?

Confirm the following information before selection:

1. Camera sensor model and sensor size
2. Camera resolution and pixel size
3. Lens mount type
4. Required field of view
5. Working distance
6. Object dimensions
7. Required inspection accuracy
8. Available illumination and exposure time

Providing these parameters helps determine whether the 16mm focal length and 1-inch image format are suitable for the application.
