HIKROBOT MVL-AF4028M-M42 — Lenses
40 mm, F2.8-F22, ⌀37 mm image circle, M42 mount

The MVL-AF4028M-M42 is a 40 mm Half Frame Lens with a wide F2.8-F22 aperture range, built on a Φ37 mm image circle that covers APS-C area scan and 4K line scan cameras. It combines a large aperture, low distortion, low chromatic aberration, and high relative illumination to target consistent image quality both wide open and stopped well down. The ability to close down to F22 makes it possible to achieve much greater depth of field when needed.

Key features
- Delivers excellent consistency of image clarity.
- Provides a large aperture, low distortion, low chromatic aberration, and high relative illumination.
- Supports a maximum image size of Φ37 mm for APS-C area scan and 4K line scan cameras.
Where it is used
The 40 mm focal length suits inspection stations where the camera sits farther from the target and a narrower angle of view is used to capture more detail, such as mid-to-long working-distance precision measurement or assembly verification lines. Being able to stop down to F22 also helps keep parts with significant depth in sharp focus.
Suitability depends on working distance, field of view, target characteristics and positioning. Selection is assessed on a per-project basis.
Is this lens right for your application?
Let us determine focal length, sensor size, working distance and field of view together, based on your application. FST is HIKROBOT’s distributor in Türkiye; product selection, commissioning and after-sales support all come from one source.
