HIKROBOT MVL-AF2045M-M42 — Lenses
20 mm, F4.5-C, ⌀30 mm image circle, M42 mount

The MVL-AF2045M-M42 is a 20 mm Half Frame Lens whose aperture ring runs from F4.5 down to fully closed (C), built around a Φ30 mm image circle that supports both APS-C-format area scan cameras and 4K, 7 μm line scan cameras. Its optical design emphasizes excellent image-clarity consistency and low distortion, both important where repeatable measurement matters. The mid-range focal length strikes a balance between field-of-view coverage and detail resolution.

Key features
- Delivers excellent consistency of image clarity.
- Provides low distortion.
- Supports a maximum image size of Φ30 mm for APS-C area scan and 4K, 7 μm line scan cameras.
Where it is used
A 20 mm focal length fits lines that need to capture both the overall shape and the surface detail of medium-sized parts in a single setup, such as packaging inspection or general metal/plastic component checks. The low-distortion optics also help in dimensional-measurement stations where geometric accuracy is important.
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.
