Detail framing on C-mount cameras

A 25 mm focal length moves MVL-KF2528M-12MP toward detail framing while retaining a Ø 17.6 mm image circle. The fixed C-mount lens provides 36.7° diagonal, 29.6° horizontal and 22.1° vertical coverage. Focus and iris are manually controlled, with an F2.8 to F16 aperture range. Optical distortion is listed at 0.4%, a stated geometric characteristic to account for when inspection points extend across the frame.

The 29.6° horizontal field fits feature measurement, code inspection and assembly checks that need a smaller angular region than the 16 mm KF lens. Minimum object distance is 0.15 m, allowing the layout to bring the camera relatively close while preserving focus. Manual settings suit a fixed station: establish the object plane, set the iris for exposure and depth, then retain that geometry. The Ø 38.6 mm × 49.32 mm lens weighs 133 g and accepts an M35.5 × 0.5 filter.

MVL-KF1628M-12MP widens the horizontal field to 44.9° at 16 mm and focuses from 0.1 m. MVL-KF3528M-12MP narrows the field to 21.4° at 35 mm and has a 0.2 m minimum object distance. Each covers Ø 17.6 mm with C-mount and an F2.8 to F16 manual iris. Choose 25 mm when 29.6° provides the required middle detail scale; step to 16 mm for more scene area or to 35 mm for tighter feature isolation.

Selection and applications

Feature measurement imaging. Code-region inspection. Focused assembly checks.

Minimum kit: The starting configuration is a C-mount camera, the MVL-KF2528M-12MP lens, a suitable cable for the camera interface, and the electrical source specified for that camera.

Nearby in the range: MVL-KF1628M-12MP — Prefer it when the wider 44.9° horizontal view at 16 mm is required; MVL-KF3528M-12MP — Prefer it for a tighter 21.4° horizontal field at a 35 mm focal length.

FAQ

What angular view values are stated for MVL-KF2528M-12MP?

The lens provides 36.7° diagonally, 29.6° horizontally and 22.1° vertically over the listed Ø 17.6 mm image. This field is tighter than the 16 mm KF lens and wider than the 35 mm KF lens.

What is the minimum focusing distance at the 25 mm setting?

The focal length is fixed at 25 mm and the minimum object distance is 0.15 m. Focus is adjusted manually at the chosen plane. Those values help establish camera stand-off before checking whether the resulting 29.6° horizontal field covers the target.

Which camera-side dimensions must match this KF optic?

Use a C-mount camera with an image area no larger than the stated Ø 17.6 mm coverage and the standard 17.526 mm flange-back condition. The lens itself measures Ø 38.6 mm × 49.32 mm and has a mass of 133 g.

How are aperture, focus and front filtering configured?

Aperture is manually adjustable from F2.8 to F16 and focus is manual. The filter connection is M35.5 × 0.5. These controls are intended to be set mechanically for the installed distance, light level, depth requirement and selected filter.

When should the 25 mm lens replace a 16 mm or 35 mm field?

Choose 25 mm for 29.6° horizontal coverage. MVL-KF1628M-12MP gives 44.9° and a 0.1 m minimum distance; MVL-KF3528M-12MP gives 21.4° and a 0.2 m minimum distance. All three cover Ø 17.6 mm.
