Narrow-field detail and neighbours

A 16 mm focal length gives MVL-HF1628M-6MPE a narrower inspection window within the 6 MP HF-E family. The fixed C-mount lens covers a Ø 9 mm, 1/1.8-inch image with angles of 31.28° diagonal, 25.94° horizontal and 17.48° vertical. Its iris operates manually from F2.8 to F16, focus is also manual, and distortion is stated at -0.018%. These values define a detail-oriented optical path without changing to a larger image format.

The 25.94° horizontal field suits localized checks of edges, small features and assembly positions where excess surrounding scene would reduce useful sampling on the target. The 0.1 m minimum object distance permits close placement when machine geometry allows. During setup, manual focus establishes the target plane and the iris sets the exposure-depth compromise. At Ø 33 mm × 31.9 mm and 56.1 g, the lens has a short mechanical envelope for a C-mount installation.

MVL-HF1228M-6MPE widens the horizontal field to 34.14° at 12 mm, while MVL-HF2528M-6MPE narrows it to 16.77° at 25 mm. Each uses C-mount, covers Ø 9 mm and provides F2.8 to F16 manual iris control. Pick 16 mm for an intermediate 25.94° view and 0.1 m close-focus limit; select 12 mm when more context is required, or 25 mm when the inspection must isolate a smaller angular region and a 0.2 m minimum distance is acceptable.

Selection and applications

Localized edge inspection. Small-feature presence checks. Close-range assembly imaging.

Minimum kit: To start imaging, pair a C-mount camera with the MVL-HF1628M-6MPE lens, the camera's required data cable, and the power supply defined for that camera.

Nearby in the range: MVL-HF1228M-6MPE — Prefer it when a wider 34.14° horizontal field is needed at 12 mm; MVL-HF2528M-6MPE — Prefer it for a narrower 16.77° horizontal view at a 25 mm focal length.

FAQ

What field angles correspond to the 16 mm focal length?

On the stated Ø 9 mm image, the angles are 31.28° diagonal, 25.94° horizontal and 17.48° vertical. This is a narrower view than the 12 mm HF-E lens and a wider view than the 25 mm HF-E lens.

What is the nearest specified focusing distance for this model?

The minimum object distance is 0.1 m. Focus is manual, so the lens must be adjusted at the actual installed distance. The stated limit is useful when placing the camera close to a localized feature while maintaining the required 16 mm framing.

Which C-mount camera format matches MVL-HF1628M-6MPE?

The lens covers a Ø 9 mm image, identified as 1/1.8 inch, and is rated for 6 MP. It uses C-mount with a 17.526 mm flange-back length. A camera should therefore be matched to that mount, image circle and optical resolution class.

How much aperture adjustment is available during commissioning?

The manual iris ranges from F2.8 to F16. Manual focus is provided separately, and the front filter connection is M27 × P0.5. These mechanical controls allow the installer to set exposure, depth of field, focus and filtering for a fixed station.

How does 16 mm positioning differ from the 12 mm and 25 mm lenses?

This lens provides a 25.94° horizontal field. MVL-HF1228M-6MPE gives 34.14° at 12 mm; MVL-HF2528M-6MPE gives 16.77° at 25 mm. The 16 mm model is the intermediate framing choice while retaining Ø 9 mm C-mount coverage.
