MC3-03X Zero Distortion MACRO lens is an opto-mechanical component
used to look at different object sizes: from 3 up to 26 mm on a 2/3”
detector (and proportionally less on smaller size detectors).
Through an adjustable knob, the desired magnification can be set and the best
focus position adjusted: once the best focus is found, the moving element can
be blocked by a screw- knob. With additional spacers, included in the
product package, it is possible to select the required range of magnification.
As the magnification increases, the Fnumber becomes higher in order to keep
a good field depth without significant compromises on image resolution and
image brightness. While the magnification changes, the distortion remains nearly ZERO,making this lens perfectly adequate for measurement applications.
A diffusive ring illuminator, perfectly fitting the lens mechanics, is
available as an accessory.
