LFHHH-1220M 12mm 10MP 4/3-Inch FA Lens | POMEAS
LFGHH-1220M is a 12mm 10MP FA lens for 4/3-inch cameras with F2.0-F22 iris, C-Mount and focus/iris locks for low-distortion imaging.
SKU:
LFHHH-1220M 12mm 10MP 4/3-Inch FA Lens
The LFHHH-1220M is a fixed focal length C-Mount industrial lens designed for 10MP machine vision cameras with sensor formats up to 4/3 inch. Its 12mm focal length, wide field angle, low distortion and lockable manual controls support stable image acquisition in automated inspection systems.
Product Overview
Built for large-format industrial imaging, the LFHHH-1220M covers an image circle of 22mm and supports sensor formats up to 4/3 inch. The lens provides an 89° diagonal field angle on a 4/3-inch sensor, allowing a broad inspection area while retaining the image detail required by 10MP cameras.
Manual focus and iris controls both include locking mechanisms to help prevent unintended setting changes after system adjustment. The standard C-Mount interface simplifies integration with compatible industrial cameras.
Key Benefits
Supports 10MP industrial cameras with sensor formats up to 4/3 inch and a 22mm image circle for detailed large-format machine vision imaging.
The 12mm focal length delivers an 89° diagonal field angle on a 4/3-inch sensor, helping cover a wider inspection area within the available installation distance.
Specified distortion is -2.4% at y=11.0mm for 4/3-inch sensors and -1.78% at y=8.0mm for 1-inch sensors, supporting controlled image geometry.
The F2.0-F22 manual iris provides flexible aperture adjustment for different illumination levels, exposure requirements and depth-of-field needs.
Separate manual focus and iris locking mechanisms help maintain the selected optical settings during continuous machine operation.

Machine Vision Applications
Large-Area Inspection
Wide-field acquisition of larger workpieces or inspection regions with compatible 4/3-inch industrial cameras.
Surface Defect Inspection
Image acquisition for detecting visible scratches, dents, contamination and other surface anomalies when paired with suitable lighting and vision software.
Dimensional Vision Tasks
Suitable for image-based dimensional and positioning tasks after the complete camera, lens and software system has been properly calibrated.
Automated Vision Integration
C-Mount compatibility and lockable manual adjustments support integration into industrial inspection equipment and automated production lines.
Frequently Asked Questions
What camera sensor size does the LFHHH-1220M support?
The lens supports industrial camera sensors up to 4/3 inch and provides a 22mm image circle. The camera must also use a compatible C-Mount interface.
Is this a zoom lens?
No. The LFHHH-1220M is a fixed 12mm focal length FA lens. Focus and iris are adjusted manually and can be locked after setup.
What is the field angle on a 4/3-inch sensor?
The specified field angle is 89° diagonal, 75.5° horizontal and 61.1° vertical. The actual object-side FOV depends on the camera sensor and working distance.
Can the lens be used with a 1-inch camera?
Yes, provided the camera uses a compatible C-Mount interface. On a 1-inch sensor, the specified field angle is 68.9° × 57.3° × 44.2° in diagonal × horizontal × vertical order.
Does the lens include focus and iris locks?
Yes. The manual focus and manual iris controls each use a locking mechanism to help maintain the selected settings during operation.
What lighting should be used with this lens?
Lighting is selected according to the material, surface, defect type, field of view and inspection speed. Please send sample images and application requirements so POMEAS can recommend a suitable lighting configuration.
Are the camera and lighting included?
No camera, light source, controller or mounting hardware is stated as standard equipment in the lens specification. Please confirm the required accessories when requesting a quotation.
Can POMEAS confirm the lens selection for my application?
Yes. Please provide the sensor model and size, pixel size, working distance, required FOV, smallest feature to inspect, available mounting space and lighting conditions.
What are the MOQ, price and lead time?
Please contact POMEAS to confirm the current price, minimum order quantity, inventory and lead time for LFHHH-1220M.
