Narrow-angle inspection placement

A 35 mm focal length gives MVL-KF3528M-12MP a narrow view while preserving the KF family's Ø 17.6 mm image coverage. The fixed C-mount lens lists 26.7° diagonal, 21.4° horizontal and 15.9° vertical fields. Its iris is manually adjustable from F2.8 to F16, and focus is manual as well. Optical distortion is -0.21%, giving a specific geometric reference for imaging small regions across the supported image circle.

The 21.4° horizontal field is suited to narrow feature bands, connector details and localized dimensional checks where a longer stand-off or tighter angular window is useful. Minimum object distance is 0.2 m, setting the nearest focusing condition for the mechanical layout. Once the object plane is fixed, focus and iris can remain at their commissioned settings. The Ø 38.6 mm × 53.61 mm body weighs 119 g, and an M35.5 × 0.5 filter can be fitted at the front.

MVL-KF2528M-12MP widens horizontal coverage to 29.6° at 25 mm and focuses from 0.15 m. MVL-KF5028M-12MP narrows it to 15.1° at 50 mm, with a 0.3 m minimum object distance. Both neighbours share C-mount, Ø 17.6 mm coverage and manual F2.8 to F16 iris control. Choose 35 mm for the intermediate 21.4° field and 0.2 m limit; choose 25 mm for more context or 50 mm for a still more restricted view.

Selection and applications

Narrow feature-band inspection. Connector detail imaging. Localized dimensional checks.

Minimum kit: A minimal station combines a C-mount camera, the MVL-KF3528M-12MP lens, the data cable for the chosen camera, and the power provision required by that camera.

Nearby in the range: MVL-KF2528M-12MP — Prefer it for a broader 29.6° horizontal field and 0.15 m minimum distance; MVL-KF5028M-12MP — Prefer it when 50 mm and a 15.1° horizontal angle give the required framing.

FAQ

What angular field does the 35 mm KF lens provide?

The specified angles are 26.7° diagonal, 21.4° horizontal and 15.9° vertical on a Ø 17.6 mm image. This positions the lens between the 25 mm model's broader field and the 50 mm model's narrower field.

How far from the object must MVL-KF3528M-12MP be focused?

The minimum object distance is 0.2 m. Since focus is manual, the actual object plane is set at installation. The distance must then be evaluated with the 35 mm focal length and 21.4° horizontal field to obtain the intended scene width.

What mount and image-circle conditions apply to the camera?

The camera connection is C-mount with a 17.526 mm flange-back length, and the lens covers a Ø 17.6 mm image. Its body measures Ø 38.6 mm × 53.61 mm and weighs 119 g, which determines immediate clearance and mounting load.

Which iris range, focus control and filter thread are supplied?

Iris and focus are both manual. Aperture spans F2.8 to F16, and the filter thread is M35.5 × 0.5. These provisions let a fixed station establish exposure, depth of field, object focus and filtering through mechanical setup.

How does 35 mm divide the 25 mm and 50 mm KF choices?

At 35 mm, horizontal coverage is 21.4° and minimum object distance is 0.2 m. The 25 mm model gives 29.6° from 0.15 m, while the 50 mm model gives 15.1° from 0.3 m. All cover Ø 17.6 mm through C-mount.
