How to choose

The image circle of 4/3″ is larger than 1.1″, so the optics are physically bigger and heavier — check in advance that the bracket holds and the protective housing has room.

FAQ

When does the 4/3-inch lens format fit the inspection task?

It fits a 4/3-inch camera arrangement that must capture a wide field of view without losing detail. The stated examples are fitting a whole pallet, sheet or roll into one frame with a 10 MP or 20 MP camera.

How are focal lengths distributed between 10 MP and 20 MP entries?

The 10 MP branch provides 12, 16, 25, 35, 50 and 85 mm lenses. The 20 MP branch provides SA1628M-20MP at 16 mm and SA5028M-20MP at 50 mm. Every entry uses C-mount and covers the 4/3-inch format.

What aperture ranges distinguish the two resolution classes?

The six 10 MP models list F2.0 to F22. SA1628M-20MP and SA5028M-20MP list F2.8. Aperture should therefore be checked together with focal length and the required 10 MP or 20 MP class.

Which listed working distances mark the ends of the 10 MP range?

The shortest listed minimum is 0.1 m for SA1620M-10MP. The longest is 1.2 m for SA8520M-10MP. Intermediate entries list 0.15 m, 0.2 m or 0.3 m, depending on the selected focal length.

What mechanical checks accompany 4/3-inch optical matching?

Because the 4/3-inch image circle is larger than 1.1 inch, the optics are physically bigger and heavier. Confirm that the bracket holds the lens and that the protective housing provides enough room.
