PMS-LFE-7258M 75mm F2.8 C-Mount FA Lens for Machine Vision
The PMS-LFE-7258M is a 75mm C-Mount FA lens designed for machine vision applications that require a narrow field of view, longer mounting distance, and detailed image capture. Compared with shorter focal length FA lenses, this 75mm machine vision lens is better suited for small-area inspection, distant camera installation, and electronic component detail observation.
With a 75mm focal length, F2.8-C iris range, 2/3" maximum sensor size, and C-Mount interface, the PMS-LFE-7258M can be integrated with industrial cameras used in automatic production, electronic communication inspection, precision positioning, and long-distance visual inspection systems.
Key Features
The 75mm focal length provides a narrow field of view, making this FA industrial lens suitable for applications where the camera needs to be mounted farther from the target while still capturing small inspection details.
The PMS-LFE-7258M supports a maximum 2/3" sensor size with an 8.8mm × 6.6mm sensor area and φ11mm image circle, helping match common industrial machine vision cameras.
The F2.8-C iris range allows aperture adjustment for different lighting environments, supporting stable image acquisition in production-line inspection and electronic component imaging.
The C-Mount interface supports integration with common industrial cameras, making the lens practical for machine vision modules, automated inspection systems, and compact equipment layouts.
The focusing range starts from 1.10m, which makes this lens more suitable for longer-distance imaging tasks rather than close-range wide-view inspection.
The listed 2/3" field of view is 6.7° × 5.0°, helping users focus on smaller target areas and reduce unnecessary background information in the captured image.
Focus and iris locking screws help maintain stable focusing and aperture settings after adjustment, reducing the risk of parameter drift during long-term equipment operation.
The compact structure supports integration into industrial camera systems that need a long focal length lens without adding unnecessary mechanical complexity.

Field of View and Lens Selection Reference
The PMS-LFE-7258M C-Mount machine vision lens is designed for narrow field-of-view imaging. With a listed 2/3" field of view of 6.7° × 5.0°, it is more suitable for small target areas, long-distance camera placement, and inspection tasks where the image should focus on a limited region rather than a wide production area.
| Selection Item | Reference Information | Selection Meaning |
|---|---|---|
| Focal Length | 75mm | Best suited for narrow FOV, longer-distance imaging, and small-area detail capture. |
| Focusing Range | 1.10m–∞ | Requires more installation distance than short focal length FA lenses. |
| Sensor Match | 2/3", 8.8mm × 6.6mm, φ11mm | Helps confirm image circle coverage for 2/3" industrial cameras. |
| Field of View | 6.7° × 5.0° | Suitable for focused inspection where the target area is small or far from the camera. |
Typical Applications
The PMS-LFE-7258M is suitable for machine vision applications where a longer focal length and narrower field of view are required. It is especially useful when the camera cannot be installed close to the object, or when the inspection area is small but needs to be captured clearly.
The 75mm focal length allows the camera to be placed farther from the inspection target while maintaining a focused view of the key area.
The narrow field of view makes this lens suitable for local feature inspection on electronic components, connectors, labels, markings, and precision parts.
In automatic production equipment, the lens can support positioning and recognition tasks where the target is small or the camera must be installed outside the immediate working area.
With 2/3" sensor support and C-Mount compatibility, the lens can be matched with common industrial cameras used in machine vision inspection modules.
Why Choose PMS-LFE-7258M?
The PMS-LFE-7258M is not intended for wide-field overview imaging. Its value comes from the 75mm focal length, narrow 6.7° × 5.0° field of view, and 1.10m–∞ focusing range, which make it more suitable for long-distance and small-area industrial inspection.
For system integrators and equipment manufacturers, this FA industrial lens helps solve applications where a short focal length lens captures too much background or cannot provide the required detail from a longer mounting distance. It can support inspection stations, electronic communication production lines, and automated vision modules that require stable narrow-FOV imaging.
POMEAS can provide lens selection support based on your camera sensor size, working distance, field of view, target size, lighting condition, and inspection accuracy requirements.
FAQ
1. What is PMS-LFE-7258M?
PMS-LFE-7258M is a 75mm F2.8 C-Mount FA lens designed for machine vision, automatic production, and electronic communication inspection applications.
2. What type of application is a 75mm FA lens best suited for?
A 75mm FA lens is best suited for narrow field-of-view imaging, longer-distance installation, and small target detail capture.
3. What camera sensor size does this lens support?
The lens supports a maximum 2/3" sensor size, with an 8.8mm × 6.6mm sensor area and φ11mm image circle.
4. What is the focusing range?
The focusing range is 1.10m–∞, so the lens is more suitable for applications with enough working distance rather than close-range inspection.
5. What is the field of view?
The listed 2/3" field of view is 6.7° × 5.0°, making it suitable for focused image capture of small or distant targets.
6. What mount type does PMS-LFE-7258M use?
PMS-LFE-7258M uses a C-Mount interface, which is widely used in industrial camera and machine vision systems.
7. Is this lens suitable for wide-area inspection?
It is not the best choice for wide-area inspection. For wide-view applications, a shorter focal length lens is usually more suitable. PMS-LFE-7258M is better for narrow-FOV and long-distance inspection.
8. How do I know whether this lens matches my camera?
Please provide your camera sensor size, required field of view, working distance, target size, and inspection requirements. POMEAS can help confirm whether PMS-LFE-7258M is suitable for your application.
