Broad coverage on a 17.6 mm image

A 12 mm focal length and Ø 17.6 mm image coverage make MVL-KF1228M-12MP a broad-view member of the KF range. The C-mount lens provides a 70.5° diagonal, 59.8° horizontal and 46.2° vertical field. Focus and iris are manual, with aperture adjustment from F2.8 to F16. Optical distortion is stated at –1.79%, giving inspection designers a defined geometric value for the wide field rather than leaving edge behavior unquantified.

The 59.8° horizontal view is applicable to larger components, multiple-feature checks and work areas that need more coverage than the 16 mm or 25 mm KF lenses provide. Its 0.1 m minimum object distance permits close positioning, subject to the required field at that distance. Manual focus sets the operating plane, and stopping the manual iris toward F16 can extend depth coverage when illumination supports it. The Ø 47 mm × 56.99 mm assembly weighs 186 g and operates from –10°C to 50°C.

MVL-KF0818M-12MP expands horizontal coverage to 77.16° at 8 mm but uses a Φ16 mm image size and a 0.3 m minimum object distance. MVL-KF1628M-12MP narrows the view to 44.9° at 16 mm while retaining Ø 17.6 mm coverage and the 0.1 m limit. Choose 12 mm for the middle 59.8° field on Ø 17.6 mm images; select 8 mm when broader coverage dominates, or 16 mm when the target should occupy more of the frame.

Selection and applications

Large-component inspection. Multiple-feature presence checks. Close-range wide-field imaging.

Minimum kit: For acquisition, use a C-mount camera with the MVL-KF1228M-12MP lens, the interface cable selected for that camera, and its specified source of power.

Nearby in the range: MVL-KF0818M-12MP — Prefer it when an 8 mm focal length and 77.16° horizontal field are needed; MVL-KF1628M-12MP — Prefer it for tighter 44.9° horizontal coverage on a Ø 17.6 mm image.

FAQ

What field angles are specified for the 12 mm KF model?

The lens lists 70.5° diagonal, 59.8° horizontal and 46.2° vertical fields on its Ø 17.6 mm image. These angles make it wider than the 16 mm KF model but narrower than the 8 mm KF model in the lineup.

How near can the inspection object be placed for focusing?

The stated minimum object distance is 0.1 m. Final focus is set manually at the installed plane. The close-focus limit, 12 mm focal length and 59.8° horizontal field should be considered together when calculating the physical scene width.

Which mechanical and optical camera interface is required?

MVL-KF1228M-12MP connects by C-mount and uses a 17.526 mm flange-back length. Its image size is Ø 17.6 mm. The lens body is Ø 47 mm × 56.99 mm and weighs 186 g, so both sensor coverage and bracket loading need to match.

What iris behavior and distortion value should be expected?

The manually controlled iris spans F2.8 to F16, and focus is manual as well. Optical distortion is listed at –1.79%. That figure can be included in geometric assessment, while the aperture is set for the required exposure and depth of field.

When does 12 mm fit better than the adjacent 8 mm and 16 mm lenses?

Use this model for a 59.8° horizontal field and Ø 17.6 mm image. MVL-KF0818M-12MP is wider at 77.16° but covers Φ16 mm; MVL-KF1628M-12MP is tighter at 44.9° and shares the Ø 17.6 mm format.
