Macro lenses for machine vision

A macro lens images a small object large: the field of view is comparable to the sensor itself. This is how connector contacts, solder joints, engraving and cutting-tool edges are inspected. Working distances across the range run from 59 to 550 mm depending on the version and the chosen magnification; focal lengths from 25 to 75 mm. A regular lens with an extension ring reaches a similar scale, but a macro lens is designed for exactly this.

How to choose

The key parameter here is magnification rather than focal length: it sets how much of the part fits in the frame, and it changes together with working distance — the table below lists them as a pair. Depth of field at this scale is small, so the object must be flat and firmly fixed.

FAQ

Why is magnification the first macro-lens parameter?

Magnification sets how much of the part fills the frame and changes together with working distance. Select those two values as a pair. The listed ranges extend from 0.1 x to 0.8 x across the specified KF models.

Which model covers the highest listed magnification?

KF5028M-ML reaches 0.8 x, the highest stated value in the family. Its full range is 0.5 x to 0.8 x, paired with working distances from 132.4 mm at 0.5 x to 95.4 mm at 0.8 x.

How do the two 75 mm macro choices differ?

KF7538M-ML covers Φ17.6 mm (1.1 inch), 0.18 x to 0.38 x and 257 to 471 mm. MVL-MF7538M-ML covers Φ11 mm (2/3 inch), 0.16 x to 0.46 x and a stated working-distance span of 250 to 550 mm.

What mechanical condition matters at macro scale?

Depth of field is small, so the object should be flat and firmly fixed. The lens-to-object position must also follow the distance associated with the chosen magnification; changing that distance changes the scale relationship.

Which aperture ranges are represented in the family?

KF2528M-ML, KF3528M-ML and KF5028M-ML run from F2.8 to F16. KF7538M-ML runs from F3.8 to F16, while MVL-MF7538M-ML runs from F3.8 to F12. Keep aperture choice aligned with format and magnification.
