vision measurement applications.
For instance, you may need to remove
possible interactions between your
machine vision LED illuminator and other
lighting sources usually present in any
industrial environment.
Moreover, sun light is very frequently
causing faults in imaging systems due to
the part being measured. In such cases
the illuminator emission wavelenghts is
usually integrated in front of the objective:
this way only the light coming from the
illuminator is collected, while the rest of
the spectrum is cut out. Besides straylight removal, many machine vision
applications require monochromatic or
pseudo-monochromatic illumination in
order to enhance or suppress some object
features: under these conditions only the
features with a certain color are imaged
and can be measured.

To overcome size and cost issues, Opto

cost-effective solution.
