Long-focal-length detail selection

The longest focal length in the standard KF group belongs to MVL-KF5028M-12MP. This fixed 50 mm C-mount lens covers a Ø 17.6 mm image and produces fields of 18.9° diagonal, 15.1° horizontal and 11.2° vertical. Focus and iris are manual, with aperture adjustment from F2.8 to F16. Its -0.05% optical distortion is explicitly characterized for inspection work that uses the restricted field for positional or dimensional detail.

A 15.1° horizontal angle concentrates the camera image on small features, codes or edge segments and also supports tighter framing from a greater stand-off. The minimum object distance is 0.3 m, so the machine layout must provide more clearance than for the 25 mm and 35 mm KF neighbours. Focus and iris are fixed mechanically after setup. The Ø 38.6 mm × 56.8 mm body has a mass of 134 g and includes an M35.5 × 0.5 filter thread for the stated front accessory interface.

MVL-KF3528M-12MP provides a wider 21.4° horizontal field at 35 mm and focuses from 0.2 m. MVL-KF5024M-25MP shares the 50 mm focal length but covers a larger Ø19.3 mm image, opens to F2.4 and gives a 15.66° horizontal field, compared with F2.8 and 15.1° here. Choose this KF lens for Ø 17.6 mm coverage at 50 mm; use the 35 mm neighbour for more context or MVL-KF5024M-25MP for the larger image circle and F2.4 maximum aperture.

Selection and applications

Small-feature detail imaging. Longer-stand-off code inspection. Restricted edge-segment measurement.

Minimum kit: The minimum arrangement uses a C-mount camera, the MVL-KF5028M-12MP lens, the selected camera's data cable, and the electrical source required by the camera.

Nearby in the range: MVL-KF3528M-12MP — Prefer it for a wider 21.4° horizontal field and a 0.2 m minimum distance; MVL-KF5024M-25MP — Prefer it for 50 mm imaging over Ø19.3 mm with an F2.4 maximum aperture.

FAQ

What field of view is associated with the 50 mm KF lens?

Coverage is 18.9° diagonally, 15.1° horizontally and 11.2° vertically on the stated Ø 17.6 mm image. It is the narrowest field among the standard KF focal lengths in the lineup and is intended for restricted framing.

What stand-off limit follows from the minimum object distance?

The nearest specified object distance is 0.3 m. The camera must be mounted at or beyond that focusing condition, and manual focus is then set on the target plane. The 50 mm focal length and 15.1° horizontal angle determine the resulting field.

Which image size and mechanical connection should the camera have?

MVL-KF5028M-12MP covers a Ø 17.6 mm image through C-mount and uses a 17.526 mm flange-back length. The lens envelope is Ø 38.6 mm × 56.8 mm with a mass of 134 g, so the camera and support should match those optical and mechanical conditions.

How are aperture, focus and a front filter set on this lens?

The iris is manual from F2.8 to F16 and focus is manual. A front filter can use the M35.5 × 0.5 thread. These fixed adjustments suit an inspection setup where working distance, target plane, illumination and filter choice remain stable.

What separates this 50 mm KF lens from the 50 mm KF-P model?

This model covers Ø 17.6 mm, opens to F2.8 and lists a 15.1° horizontal field. MVL-KF5024M-25MP covers Ø19.3 mm, opens to F2.4 and provides 15.66° horizontally. Their minimum object distances are 0.3 m and 0.25 m.
